Method for growing
Two different strains of Cordyceps sinensis are placed at two different locations in a medium containing purified rattle snake venom and the two strains are allowed to grow until they meet in a boundary zone where a hybrid strain is formed due to exchange of genetic material. The hybrid strain is allowed to grow and is harvested and can be analyzed for the presence and quantity of desired medicinal substances. The amount of N 6 -(2-hydroxyethyl)-adenosine in a Cordyceps sinensis strain or product sample is a reliable indicator of the overall health benefiting qualities of the strain or sample. Strains of Cordyceps sinensis , are grown in a substrate at 20 to 22° C. at sea level atmospheric pressure for 28 to 30 days in diffuse light, and thereafter in an atmosphere containing approximately 50% of oxygen of the sea level atmosphere, at approximately 3° C. with exclusion of light, for approximately 15 to 20 weeks to provide a Cordyceps sinensis product that has the characteristic analytical signature of wild Cordyceps sinensis and includes substantial quantities of the health benefiting compounds of the strain found in the wild.
1. A method of growing Cordyceps sinensis , comprising the steps of:
growing said fungus in a substrate at approximately 17 to 25° C. at an atmospheric pressure which is in the range of approximately 10% below to approximately 10% above normal sea level atmospheric pressure for approximately 25 to 33 days in diffuse light, and
thereafter growing said fungus in an atmosphere containing approximately 45 to 55% of oxygen of normal sea level atmosphere, at approximately 2 to 4° C. with exclusion of light, for approximately 13 to 22 weeks.
2. A method of growing Cordyceps sinensis in accordance with claim 1 , comprising the steps of:
growing said fungus in a substrate at approximately 19 to 23° C. at an atmospheric pressure which is in the range of approximately 5% below to approximately 5% above normal sea level atmospheric pressure for approximately 27 to 32 days in diffuse light, and
thereafter growing said fungus in an atmosphere containing approximately 47 to 53% of oxygen of normal sea level atmosphere, at approximately 2 to 4° C. with exclusion of light, for approximately 13 to 22 weeks.
3. A method of growing Cordyceps sinensis in accordance with claim 2 comprising the steps of:
growing said fungus in a substrate at 20 to 22° C. at seal sea level atmospheric pressure for 28 to 30 days in diffuse light, and
thereafter growing said fungus in an atmosphere containing approximately 50% of oxygen of the sea level atmosphere, at approximately 3° C. with exclusion of light, for approximately 15 to 20 weeks.
