Pine Bark Extract

Maritime French Pine Bark Extract Supports the body’s natural defenses against premature aging. Primarily it is used for cardiovascular health, blood circulation, normal blood pressure support and healthy blood.  Nitric Oxide NO is a chemical that is responsible for blood vessel dilation. As we age this can be affected leading to kidney, heart, erectile dysfunction, cramps, cold hand and feet and brain clarity.

Pine bark has also been used to support clear airways, skin health because of its antioxidant effect on inflammatory chemicals.


This herb is used in traditional Chinese medicine systems. Cordyceps is used as an “all illness” tonic to support  energy, blood sugar levels, stamina, libido, endurance and sleeping patterns.

In certain areas of the Himalayan mountains the traditional healers prize Cordyceps as a precious longevity promoting herb. In 1993 Chinese track and field athletes cracked many world records, so they were tested for drugs. They were cleared of any suspicion. But their coach finally had to  gave his secret away.

Korean Ginseng Root

New ground in life science and technology now presents us with genomic and proteomic revolution.  High performance liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS) used for separating and identifying new chemical can be applied  to the traditional Chinese medicine (TCM). This opens a new chapter in the ancient medicine, and has prompted scientists to re-evaluate the thousand-year-old phytomedicine–ginseng from current perspectives.

Stress-induced fatigue

Fatigue is considered an alarm phase of the adaptive defense response of the neuroendocrine-immune system to stressors [1]. Fatigue, also known as weariness, tiredness, exhaustion or lethargy, is a common health complaint that may be generally defined as a lack of energy. Fatigue and sleepiness can affect performance at work and cause transportation and industrial accidents, resulting in considerable losses of property, personal injury and even death . It is estimated that approximately 20% of Americans experience fatigue of sufficient intensity to interfere with the ability to enjoy a normal life, with physical causes being responsible for 20%-60% of fatigue cases and emotional causes being responsible for the balance.

Fatigue can have a physical and/or mental nature. Physical fatigue, also known as peripheral fatigue, results from repeated muscle actions followed by an inability to continue functioning at a level commensurate with normal ability. By contrast, mental fatigue represents a failure to complete mental tasks that require self-motivation and internal cues in the absence of cognitive failure or motor weakness. Mental fatigue decreases the efficiency of subjects’ occupational work or learning effectiveness in daily life. Mental fatigue may manifest in the form of decreased attention, reduced concentration, or somnolence. Acute fatigue is a normal phenomenon that disappears after a period of rest. Conversely, prolonged fatigue is often irrevocable, and the recovery mechanisms that alleviate acute fatigue are no longer effective. Chronic fatigue is caused by the prolonged accumulation of acute fatigue. It is well known that social stresses frequently trigger acute mental fatigue and the onset of chronic fatigue syndrome [1]. Dealing with the COVID-19 viral outbreak has created a tremendous amount of constant stress directly related to the outbreak plus the implications of the lock down, and other restrictions that are put in place as a way to contain spreading of the virus. Stress is caused fighting the virus or worrying about a family member or yourself that you may be the next victim. There could not be more stress for people today who are losing their jobs without knowing if they have an income to meet the challenges of paying the mountain of bills piling up. Just the uncertainty of what the future will hold for millions of people can cause stress and stress-induced fatigue. The stress today may take a greater bodily toll than the virus itself.

Many people prefer to avoid problems related to decreased attention and reduced concentration during continuous mental work and resort to the use of stimulants (caffeine), sympathomimetics (ephedrine) and tonics such as cola. However, regular consumers of coffee recognise that caffeine can disrupt sleep and that caffeine withdrawal is associated with various adverse effects including fatigue and headache. Cognitive performance is adversely affected by acute caffeine withdrawal, and even in the context of alertness reduced by sleep restriction, cognitive performance is not improved by caffeine in the absence of withdrawal effects. Because caffeine use is also associated with an increased risk for various cardiovascular diseases including high blood pressure and elevated plasma homocysteine levels, it has been suggested that caffeine consumption confers little benefit. Additionally, the diterpenes present in unfiltered coffee also appear to increase the risk of coronary heart disease [5,6]. The use of sympathomimetics might efficiently improve acute fatigue; however, their long-term use might accelerate the progression of chronic fatigue because sympathetic hyperactivity based on decreased parasympathetic activity is associated with mental fatigue induced by prolonged cognitive load.

Many plant extracts have exhibited good balancing and anti-fatigue effects in experiments conducted in experimental animals. Of these, adaptogens (Panax ginseng, Rhodiola roseaEleutherococcus senticosus ~(REZENERGY)Schisandra chinensis- OLE-UP) have exhibited significant anti-fatigue effects including increased mental performance, particularly cognitive function, in placebo-controlled, double-blind studies [7]. These adaptogenic plants extracts can enhance resistance to stress and improve performance, concentration, and endurance during fatigue [8-15]. 

Traditional and current uses

Ginseng root has been traditionally used in China, Korea, and Japan for thousands of years “to tonify the original qi greatly, resume pulse and secure collapse, tonify [the] spleen and replenish [the kidneys], engender fluid and nourish blood, tranquilise the mind and replenish wisdom” [1].

The first medical records on efficacy of Ginseng, also known as Korean ginseng, are dated 200 CE, and its use was later summarized (in 1596 and 1959) in Chinese Materia Medica. Ginseng has been used to promote vitality and healthy ageing, to enhance cognitive function, reverse general weakness, improve blood circulation, and restore normal pulse in subjects with palpitations. According to ancient records, long-term ginseng uses longevity and  mental and visual performance. However, ginseng has been used primarily as a tonic to invigorate weak bodies and help restore homeostasis, a modern term associated with adaptive stress syndrome, adaptability and adaptogen concepts [1].

The effectiveness of ginseng has been recognised in the West since the 18th century. Ginseng has been used as a general tonic or adaptogen to promote longevity and support normal fatigue and mental stress. Based on its multiple health applications, including increased energy, improved cognition, enhanced immunity, reduced blood sugar levels, better circulation for women and men with benefits for sexual health in men, Korean red ginseng is often considered an all-encompassing remedy by herbalists

Siberian Ginseng

Historically, Siberian ginseng has been used by Chinese herbalists for over 2000 years  to support immune resistance, vitality and energy. It has also been used by the Russian’s to support their cosmonaut’s energy levels and help them to cope with the stresses of life in space as well as by their athletes. Although the common name is Siberian ginseng, this wonderful herb comes from a different herbal family altogether. In herbal medicine Siberian ginseng’s main action is an adaptogen, which means it supports the body in times of stress and allows the body to cope with environmental factors (these could be physical or psychosocial) without damage.

Human clinical research in 1000 factory workers in Siberia showed the herb can support the immune system, reduce general illness and absenteeism. Siberian ginseng is considered as a tonic in times of stress and debility. More human research on recreational athletes showed 8 weeks of Siberian ginseng targeted physical endurance and cardiovascular function.

In a large clinical trial involving a group of elderly people Siberian ginseng was found to support their overall quality of life. Other studies have found the herb supports endurance and mental performance in patients with mild fatigue and weakness.
