Mushroom Science Cordyceps Cs-4 Extract (Cordyceps sinensis)

For Energy & Endurance

Cordyceps sinensis is a highly valued medicinal mushroom in both Classical Chinese Medicine and modern clinical practice. In China it is called "winter worm, summer grass", and the "caterpillar mushroom" (aka: Dong Chong Xia Cao). Cordyceps is found in the highlands of China, Tibet, and Nepal, above 10,000 feet.

Cordyceps attracted the attention of the general public and the health profession in 1993 when a group of Chinese runners broke nine world records in the World Outdoor Track and Field Championships in Germany. Afterwards the coach attributed those results to the athletes regular use of a cordyceps based tonic. Because Cordyseps helps increase stamina, energy levels, and endurance, it has become one of the top selling sports supplements amongst the worlds' elite competitive athletes.

Clinically, Cordyceps is used to support immune health.

Cordyceps Sinensis Cs-4

The wild fruiting form of Cordyceps used in Traditional Chinese Medicine is extremely rare in the wild and because of this it is very expensive. Chinese scientists spent many years looking for a vegetative form of Cordyceps that would produce the same active compounds as the fruit body; the result of that research is the Cordyceps strain Cs-4.

All of the published clinical research has been conducted with hot water extracts of the mycelium of the Cs-4 strain of Cordyceps, the same strain Mushroom Science uses to produce their high potency extract.

Clinical Research

There has been a significant amount of research done on Cordyceps. Studies have looked at the immuno-modulating and immuno-regulating activities, uses in supporting renal health and respiratory health.

Traditional Use and Preparation

Cordyceps is sweet and acrid in taste and warm in nature, acting through the lung and kidney channels.Cordyceps invigorates the kidneys and protects the lungs. Cordyceps is also used in cases of occasional fatigue. For most conditions Cordyceps is prepared as a decoction, although when used as a tonic in TCM the fruit bodies are often cooked into a chicken broth.

Extraction Information

Wild Cordyceps sinensis fruit bodies and cultivated Cordyceps sinensis mycelium have demonstrated equal levels of immune activity, neither being superior to the other.

Mushroom Science's product is a hot-water/ethanol extract from the Cs-4 strain of Cordyceps. The mycelium is cultivated on an all-natural chemical-free nutrient base. This process yields all of the active constituents that make Cordyceps one of the most highly prized medicinal mushrooms.

Hot Water Extracted: Dr. Mark Stengler N.D., in his recent book, The Health Benefits of Medicinal Mushrooms, made the observation that all of the independent scientific studies on medicinal mushrooms are based on the use of hot water extracts. All of the references from Traditional Chinese Medicine also recommend hot water extraction when preparing medicinal mushrooms. There are two main factors involved:

Bioavailability - The immune-supporting polysaccharides common to all medicinal mushrooms and mushroom mycelium are found inside of the cell walls. However, the cell walls are made from an indigestible fiber called "chitin", the same material a lobster shell is made of. Hot water extraction is the only clinically validated method for breaking these polysaccharides out of the indigestible cell walls. Even soft mushrooms like shiitake are prepared as a hot water extract or a tea when used medicinally.

Concentration - The immune supporting polysaccharides found in the cell walls of mushrooms and mushroom mycelium comprise only 0.5-2% of the total mass by dry weight (depending on the mushroom), not enough to have effect even if they were bioavailable. Most hot water mushroom/mycelium extracts are at least a 20:1 concentration. Hot water extraction dissolves the indigestible fiber (chitin), allowing the fiber to be removed from the extract when the water is removed. This process concentrates the polysaccharides to the effective levels identified in the published research.

Hot water extracts (dehydrated) are 50-80 times more potent than tinctures (cold water extracts) or mycelium biomass.

  • • Every extract is carefully prepared, capturing the complete essence of what made these medicinal mushrooms valuable in the ancient herbal traditions of Japan and China.

While medicinal mushrooms have been used for thousands of years in Traditional East Asian Medicine, rigorous scientific testing on the use of these mushrooms has been conducted only in the past thirty years. However, those thirty years of research have produced a wealth of information. They find that on all of the important points, science supports the preparation and use of medicinal all-natural mushrooms as described in the texts on Traditional Chinese Medicine.

This knowledge, a point of convergence between the clinical traditions of East and West, is the foundation of their approach to quality, and guides every step of their manufacturing and quality control process.
