The circulatory system, also called the cardiovascular system, is an organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide and hormones to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, which is a blood vessel “loop” through the lungs where blood is oxygenated; and the systemic circulation, which is a blood vessle “loop” through the rest of the body to provide oxygenated blood. The systemic circulation can also be seen to function in two parts–a macrocirculation and a microcirculation. An average adult has five to six quarts (roughly 4.7 to 5.7 liters) of blood, accounting for approximately 7% of their total body weight. Blood consists of plasma, red blood cells, white blood cells, and platelets. Also, the digestive system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.

The cardiovascular systems of humans are closed, meaning that the blood never leaves the network of blood vessels. In contrast, oxygen and nutrients diffuse across the blood vessel layers and enter interstitial fluid, which carries oxygen and nutrients to the target cells, where carbon dioxide and wastes diffuse in the opposite direction.

Schizandra has the potential to boost your cardiovascular system in several ways. It is very beneficial to your lungs and will greatly enhance pulmonary circulation. It has even been taken for asthma complaints. Not only does schizandra help with good blood flow but will help your body maintain healthy levels of blood sugar and blood pressure, as well as lower your cholesterol. It has been used to ease coughing and increase energy and endurance, making it quite the powerful supplement for people with upper respiratory issues, such as asthma.

Schizandra has been proven through many tests administered throughout the century to improve Mental capacity, concentration and memory on many different levels. In general, Its stimulation on the central nervous system gives your brain a renewed sense of focus, but Science has shown so much more in relation to what Schizandra actually can do for mental function. Due to it’s complex affect on the entire bodily system, it has the ability to increase overall work productivity.

In one study, Schizandra was also shown to improved tolerance to oxygen deficiency. In another study, the berry was shown to lower blood glucose after strenuous physical activity, which helped obtain overall mental and physical stability.

In two sets of experiments in the 1950’s, young telegraph operators were asked to transmit Morse code at maximum speed for a period of 5 min, and the frequency of errors was measured. It was concluded that Schizandra preparations prevent or reduce exhaustion related errors in a manner similar to that observed following treatment with Ginseng. When put up against a placebo, Schizandra was again found to be beneficial in preventing exhaustion related errors because when administered at a dose of 3.6 mg, error levels fell to 95% relative to the control, where the frequency of errors in the placebo group was estimated at 228%.

The effects of Schizandra on visual memory, dimensional imagination and perception, distribution and switch of attention, arterial blood pressure and frequency of heart contractions were evaluated through various experiments in the 1990’s in a placebo controlled study involving 59 stewardesses. Participants were tested before and after long haul (7–9h) flights and the results revealed that the administration of Schizandra significantly improved all of the assessed parameters.

As seen here, science has had an in depth look at the affect of Schizandra on Mental performance over the last century. These studies and many more have confirmed it’s incredible affect on all levels of mental capacity and function.

When the body is exposed to increase Altitudes, the pressure in the surrounding atmosphere decreases. The number of people travelling to the high altitude regions, especially South America, Nepal, and India, has risen enormously in the past 10 years, and many have experienced struggle or health issues because of the difficulty in adjusting to the changes in pressure. Many are under the impression that oxygen levels decrease at higher altitudes, but actually, the level is consistent at all altitudes that humans would venture to on earth, but rather the ability for our lungs to transfer the oxygen from our lungs is decreased at lower pressures. This is where Schizandra has been seen to once again act as a savior in stressful conditions. Schizandra has been seen to increase the body’s ability to optimize the uptake of oxygen from the lungs to the blood. Having this pathway opened up was seen to counteract the change in pressure experienced by the lungs at high altitudes, allowing the body to experience the results of more oxygen intake, which is greater endurance and stamina.

Similarly, in areas of high air pressure, the body’s ability to uptake oxygen is also decreased when the body is under physical activity, as in the case for swimmers or scuba divers. The body responds to the pressure change with a decrease in power requirements, taking less oxygen, but the body actually feels a lowered aerobic activity. It was seen that after Schizandra administration, a similar result was experienced as in lower pressure environments. The body and lungs were able to absorb more oxygen allowing the athletes to experience normalized endurance.

As a top level adaptogen, one of Schizandra’s best qualities is that it plays a big role in bringing the body into balance: hormonal balance, chemical balance, and internal balance with the surrounding environment. Creating balance means one can perform better under stressful conditions on all levels of physical, mental and emotional activity. Within the body’s incredible complexity, the affect of Schizandra on specific kinds of stress have been tested. The stress experienced from extreme heat and cold conditions were both seen to be improved by administration of Schizandra, in some cases only after 1 dose.

In several studies, first in the 60’s and then in the 80’s it was seen that after the administration of Schizandra the body continued to function during a rise in external heat conditions far better then when the herb was not taken. It was seen to have a somewhat protective affect to allow a greater tolerance to otherwise damaging conditions.

A similarly positive affect was found when testing Schizandra’s ability to help the body deal with stress from extreme cold conditions.  A dose of Schizandra one to two hours prior to the stress in extreme cold water swimming conditions decreased the resistance to fatigue. In these experiments, it was also seen that Schizandra

prevented the development of atrophy of the adrenal glands, which means that adequate hormone was still being produced even under this extreme stress.

In addition, it was also seen that Schizandra could contributed to a decrease in frostbite consequence if taken prior to any drop in temperature. This effect appeared to be associated with Schizandra’s ability to increase oxygen in cells, since frostbite is known to be a consequence of local oxygen insufficiency in the skin tissue.

The human gastrointestinal tract, or GI tract, is an organ system responsible for consuming and digesting foodstuffs, absorbing nutrients, and expelling waste.

The GI tract consists of a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine and anus. Food enters the mouth, travels through the tract and passes to the anus through the hollow organs of the GI tract. During its journey through the GI tract, digestion occurs.

Bacteria in the GI tract, also called gut flora or microbiome, are responsible for healthy digestion. Parts of the nervous and circulatory systems also play roles in the digestive process. Together, a combination of nerves, hormones, bacteria, blood, and the organs of the digestive system completes the complex task of digesting the foods and liquids a person consumes each day, turning it into vital energy for the body to use to keep it alive.

Digestion is vital for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins.

Like all systems in the body, when the GI tract is out of balance or unhealthy, the body simply cannot function properly. When digestion is impaired, a person can feel intense fatigue and pain, and if it is prolonged it can lead to numerous health conditions.

One common imbalance of the GI tract is too much or too little stomach acid. This is caused by stress, disease or the imbalance of other systems. Schizandra was shown to reduce excessive acid, and to increase acid when there wasn’t enough because it’s adaptogenic qualities and it’s overall balancing affect on all of the bodies organs and systems. Having a neutralizing affect on the blood means it automatically brings balance where imbalance is present.

The main function of the endocrine system is to serve as our body’s message center. The endocrine system is made up of endocrine glands, and these glands secrete hormones into our blood or surrounding interstitial fluid (the fluid that surrounds our cells). These hormones deliver messages and the endocrine system coordinates the messages. Hormones vary in their chemical structure, depending on the endocrine gland they are secreted from.

Our endocrine system works closely with our nervous system to maintain proper function. Most body organs are influenced by the nervous system and the endocrine system. The nervous system sends messages through nerve impulses, whereas the endocrine system sends hormones as messages. For example, a muscle contracts in response to never impulse. The secretion of epinephrine (adrenalin) helps to make the contraction stronger and more forceful to help sustain it.

Without proper endocrine function, our bodies cannot maintain proper hormonal balance. The health of our endocrine system is essential to our ability to function properly. Our cells are genetically programmed to only receive and respond to messages from certain hormones. Hormone levels can be influenced by stress, fluid changes in the body, minerals in the blood and infection. Each endocrine gland plays a specific role in the ability of our body to maintain proper function. Each endocrine gland also communicates with the other in an amazing design. If one of the endocrine glands is not functioning properly, it may cause a broken link in communication with other endocrine glands or actions of the body, which may greatly impair health.

This is where Schizandra as an adaptogen comes in. Adaptogens, as we have seen are a classification of plant with incredible health and balancing affects on the body’s intricate system. Adaptogen herbs are nourishing to the entire endocrine system of glands. Since adaptogens increase resistance to mind-body stress, enhancing overall vitality and health, one of the biggest affects they have on the endocrine glands is reducing the harmful affects of stress on hormone production and release. Schizandra as an adaptogen helps to normalize the bodies hormone production even during diseased states. And since it is non-toxic and highly nutritive, it also acts as a nourishing strengthener to the entire endocrine system.

When we experience chronic stress symptoms, we often find that our immune system becomes compromised and less able to fight infection. In fact, one of the worst effects of chronic stress is that it suppresses the immune system. Most people are aware of this because when they become stressed and run down, they often get a cold.

In addition, where this stress can be emotional or work related, it can also include environmental factors like weather or poor air quality.  Schizandra berry has a good reputation in aiding the immune system when it is affected by ongoing, chronic stress of all kinds. Early studies have demonstrated that Schizandra can reverse the negative effects of stress on the immune system and prevent the immune suppression caused chronic stress when taken as a preventative supplement.

Schizandra is one of the adaptogenic herbs that is helpful to assist countless health issues that are related to both immune health and long term chronic stress. This includes colds and flu symptoms, chronic fatigue syndrome, chronic coughing, and much more. When the body is stressed, it releases a stress hormone called cortisol. If you are stressed for a short period of time, the amount of cortisol released is not a problem. However, if you are stressed long term, prolonged, elevated levels of cortisol directly cause a suppressed immune system as well as heart disease, obesity and can even shrink parts of your brain. While the elimination of the stress is always the best treatment, consuming Schizandra can reduce the stress and elevated cortisol on your body, and therefor bring down all of its ill affects on the immune system and general body health.

In addition, Schizandra is a Qi tonic considered particularly beneficial for the Lung organ-meridian. This part of the organ meridian system in Chinese medicine is known to be responsible for the production and distribution of Defensive Qi, ie, the Qi that governs the immunse system. Schizandra is also  traditionally regarded as helping to gather together exhausted Qi, causing overall balance for the body to regain momentum toward it’s own natural health.

The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. Like a central computer, it interprets information from all of our bodily senses and internal organs.

The spinal cord is the highway for communication between the body and the brain. When the spinal cord is injured or impaired, the exchange of information between the brain and other parts of the body and senses is disrupted. Even when the central nervous system is affected by minor stress, over stimulation, or exhaustion, a person can feel clumsy, uncoordinated or disoriented.

Schizandra is known for it’s balancing affect on the body’s systems and for it’s role as an important adaptogen in the world of natural pharmacology. An adaptogen is a remedy that reduces the effect of stress on the body by reducing the production of stress hormones from the adrenal glands. Schizandra has been proven be countless studies to be a particularly helpful adaptogen in its ability to have a strong impact on the nervous system.

Schizandra was shown to have a beneficial effect in balancing the nervous system to produce a healthy, normalizing response to stress, even after traumatic conditions. It produces a healthy stimulation to all levels of the central nervous system, but unlike stimulants, it does so in a non-stressful manor.

Adaptogens, differ in significant ways from classical Central Nervous System stimulants. Experiments have shown that adaptogens do not have direct anti-narcotic effects on the CNS unlike other stimulants such as phenamine or caffeine. The mechanisms of action of adaptogens to the CNS are related to the regulation of stress affects, which in term support the body’s natural balance and energy flow. They are associated with the biochemical adaptation of cells to this stress. Stimulants on the other hand, produce an almost artificial surge of energy, resulting in potential burn-out and increased long term stress.

Below is a common graph that outlines the general differences to be expected of stimulants and adaptogens on the CNS.

Stimulants Adaptogens
Recovery process after exhaustive physical load Low High
Energy depletion Yes No
Performance in stress Decreased Increased
Survival in stress Decreased Increased
Insomnia Yes No
Side effects Yes No
DNA/RNA and protein synthesis Decreased Increased

Schizandra has been a mainstay of traditional Chinese medicine for centuries. It’s considered to be one of the 50 fundamental herbs and has been used to treat a host of conditions by millions and millions of people. It has a long history as a tonic herb to improve mental and physical health and well-being.

In general, Schizandra is an adaptogen. That means it promotes a healthy balance in the body, rather than tipping the balance one way or the other. That’s very different from the way a stimulant works. Both an adaptogen and a stimulant might increase a person’s energy levels. The adaptogen does it by supporting the body’s natural systems, such as the respiratory and circulatory systems. The stimulant, on the other hand, forces the body to work at an unsustainable level. Ultimately, there will be side effects from stimulants, as the body has to recover from this stress. But because Schizandra works with the body, it causes none of these ill effects. What it does cause are lots of good ones.

Modern science has proven the many benefits of Schizandra. These include enhanced:

  • Mental Performance
  • Endurance and Working Capacity
  • Accuracy of Movement
  • Stress Response: Heat/Cold, Altitude/Air Pressure

Benefits To Bodily Systems:

  • Central Nervous System
  • Endocrine System
  • Immune System
  • Gastrointestinal System
  • Cardiovascular System

Mental Performance

It’s hard to concentrate when you’re tired, and accidents are bound to happen. They can be serious, such as when drivers fall asleep at the wheel. Usually, we reach for a coffee or other mild stimulant to keep us going. But stimulants just delay the inevitable—they give you a temporary boost, but when they wear off, you are more tired than ever.

Schizandra was tested to see if it could reduce mistakes when people were tired or had been working for a long time. In two studies by Lapajev, Schizandra was shown to reduce mistakes in tired people. The studies also showed that Schizandra helps people to study effectively, even when tired. Since this is what most students do days before their exams, Schizandra could be quite beneficial to them!

Schizandra can also help people to concentrate, to remember visual concepts and verbal ones, and to maintain their balance. If you have ever felt a little wobbly after staying awake too long, you’ll know that tiredness can have a big effect on balance. Schizandra helps to counteract that!

Reading text on a screen can be tiring. Most of us spend some time on the Internet regularly, but there are some professions that require constantly staring at the screen, for 6 or more hours per day. Often this leads to eye fatigue, and can affect vision over time. This takes on an extra dimension when you consider that some professions, such as air traffic control, require high performance and cannot allow for mistakes. The studies showed that Schizandra increases resistance to visual fatigue, which makes it essential for people who must work with screens.

Endurance and Working Capacity

In terms of physical endurance, there are two factors to measure. Static load is when an animal or person is resisting a force without moving. An example would be holding up a weight. A dynamic load would be resisting a force while moving. Running is an example of a dynamic load (resisting gravity, friction and inertia). Sometimes an herb will help with one type of load, but not another.

Schizandra has been demonstrated to be effective in improving performance and endurance under both types of load. It appears to work by improving the body’s ability to use oxygen efficiently, and also increasing the amount of hemoglobin (which carries the oxygen in the blood). These findings were published in papers by Lupandin and Lapajev, and also by East China Jiaotong University in Nanchang City.’

Accuracy of Movement

Learning new skills and performing with finesse require the ability to move the body accurately. Most people have pretty good coordination but surgeons, athletes, pilots, and performers typically have excellent coordination. It’s a variable quality between people, and also in one individual. Even athletes and brain surgeons have off days!

Schizandra was proven to aid the accuracy of movement in a study conducted by Lapajev in 1978. The best performance was seen when the subject took preparations made from the seed of the plant.

Stress Response

Stress is known to produce many reactions that seem unrelated to the source of the problem. For instance, a worker worried about his job security might start to develop stomach ulcers or lose weight. Stress attacks several important systems in the body, including the immune system; it attacks the tissues of the thymus, one of the immune system’s primary organs. That’s why stress is indicated as a major cause of many different illnesses and health conditions.

Stress leads to the release of chemicals in the body that cause adverse reactions. An example is adrenocorticotrophic hormone, which plays an essential role in metabolism and immune response. When too much is present in the body, it can start to have harmful effects, especially on the adrenal gland.

Other substances within the body increase blood flow, helping the muscles to perform more efficiently during times of danger. An example is nitric oxide, which also plays a role in immune responses and allergies.

Schizandra was demonstrated to increase the quantities of nitric oxide in athletes during a trial by Panossian in 1999. The athletes also had improved performance and increased stamina. Schizandra has been shown to be effective in combating the harmful buildup of these stress mediators in mice in trials by Lupandin and Lapajev in 1981, and Barnaulov and Shanin in 1991.

So Schizandra helps to release the chemicals needed to perform well under stress and then helps to prevent them from building up to toxic levels! This is clearly a case of the adaptogenic properties of Schizandra; adaptogens promote balance.

In addition to such tests examining the general stress mechanisms, several studies also have documented the effectiveness of Schizandra against specific types of stress:

Hot and Cold

Hot and cold are environmental factors that can exert great stress on the body. Both can kill, but they affect the body in completely different ways. The question is, can Schizandra help with either or both of these stresses?

To answer this question, scientists would have to test both hot and cold separately. Lupandin and Lapajev tested Schizandra’s usefulness in hot conditions in 1981, and Lebedev and Kamilov followed up in 1966.

They learned that Schizandra could help us to survive under extreme heat, reducing the death rate. Also, it helps to maintain endurance in hot conditions. It’s possible to keep swimming for longer after taking Schizandra.

Separate studies (again by Lupandin and Lapajev) looked at cold conditions. Schizandra can help to prevent damage from cold and it can also improve performance under cold conditions. To get the most benefit, the Schizandra must be taken before exposure to cold conditions.

It can even help to combat frostbite. In frostbite, cell death is caused by a lack of oxygen, as well as damage caused by the expansion of water in freezing cells. Schizandra reduces the cells’ demands for oxygen, which means they can last longer with less. That helps to reduce the damage caused by frostbite.

Altitude/Air Pressure

High and low air pressure are another source of environmental stress. Schizandra dramatically increases the body’s resilience to high air pressure, making you more likely to survive pressures that would otherwise kill you. Scientists think this happens because the brain and liver require less oxygen after taking Schizandra.

Under low-pressure conditions, Schizandra improves stamina by almost three times! It’s possible to keep swimming or running under low air pressure with Schizandra. These results were published by Konstantinov and Belonosov in the Fifties, and by Lupandin and Fruentov in 1968.

Pressure changes can be a factor in extreme sports. Climbing, diving, skydiving, and aerobatics all involve changes in air pressure. One of the great dangers is blacking out under pressure, and suffering injuries or death because of accidents. It would be beneficial for athletes and extreme sports enthusiasts to use Schizandra to improve their resistance to high and low pressure.

Bodily Systems

As recognized by Western science, the body is made up of many different systems that cooperate to keep us alive and functioning well. Schizandra was examined to see if it helped these systems. The results support the history and modern use of Schizandra as an adaptogen and all-around health tonic.

Central Nervous System

The central nervous system plays the critical role of relaying messages to and from the brain. Without it, you cannot move or feel. When the central nervous system is impaired, you feel clumsy and uncoordinated. You may feel numb or experience strange pains. Your nervous system can also be overstimulated, causing twitches or over-sensitive reflexes. These are typical drug effects, but illnesses and exhaustion can produce similar effects.

Schizandra was shown to have a beneficial effect in balancing the nervous system to produce a healthy, normal response, even after traumatic conditions.

More..

Endocrine System

The endocrine system comprises the various glands responsible for controlling organic function in the body. They release hormones into the blood and control the way your organs function. When they are working well, the body is healthy and efficient. Endocrine problems can cause strange organic effects, illness and disease. Eventually, they can lead to death.

Schizandra supports several parts of the endocrine system. It helps the adrenal glands to resist harm from physical stress and the side effects of testosterone and hydrocortisone.

It also helps to balance blood sugar levels and blood acidity. Researchers believe this is due to the effects that Schizandra has on the metabolism of carbohydrates, fat, and protein. It is the byproducts of these metabolic processes that alter the blood sugar and acidity.

More..

Immune System

Schizandra has been shown to reduce excessive inflammation and fever, both of which are immune system functions. Excessive inflammation is a factor in a host of immune-system-related illnesses, allergies, and other conditions. It can be very painful or even life-threatening. Schizandra was effective as a treatment (after the inflammation began) and as a prevention (it stopped the inflammation from happening).

Also, Schizandra is a powerful anti-oxidant. Oxygen free radicals can harm the body and the immune system. By reducing them, Schizandra aids the immune system and reduces possible illnesses caused by radicals.

More..

Gastrointestinal System

Too much stomach acid or too little are both bad conditions, and can cause problems if they are not remedied. Schizandra was shown to reduce excessive acid, and to increase acid when there wasn’t enough.

As an adaptogen, Schizandra works to maintain a healthy balance in the gastrointestinal system.

More..

Cardiovascular System

The cardiovascular system is essential to the continued functioning of the organs in the body. Therefore, any problem with the cardiovascular system can affect organs all over the body, causing a variety of problems to arise.

Schizandra aids breathing, blood flow and heart action. It reduces blood pressure and promotes healthy circulation.
