I read it was fungus from a certain caterpillar.... and it is a veritable panacea. Needless to say I bought a bunch of bulk Cordyceps when I read that.... ... ding ding ding... here's a write up that I found while posting this.
Description-- Cordyceps is a Chinese mushroom used in Traditional Chinese Medicine (TCM) for “lung protection” and “reproductive invigoration” as well as to balance the “Qi” – the fundamental “energy of life.” Cordyceps is also known as the Chinese caterpillar fungus (yuck!) because it is a parasitic organism that grows on a rare Tibetan caterpillar until the caterpillar dies and the mushroom sprouts from the caterpillar’s head (double yuck!!). Luckily, the source of cordyceps used in most modern supplements is not pulverized caterpillar heads, but a strain grown on soybeans or other less disgusting nutrient source.
Claims---
Relieves asthma
Increases lung function
Boosts libido and sexual function
Improves athletic performance
Theory--- Cordyceps could be the next Ginseng due to its reported effects on increasing energy levels, sex drive and athletic performance. You may remember mention of cordyceps in the news a few years ago when several Chinese athletes came from out of nowhere to break world records in swimming and running. It turns out that the athletes were following a supplementation regimen that included cordyceps. Although the pharmacologically active components of cordyceps remain unknown, at least two chemical constituents; cordycepin (deoxyadenosine) and cordycepic acid (mannitol) have been identified and suggested as being the active compounds in improving lung function and increasing energy levels and sex drive.
Scientific Support-- Although a number of studies have been conducted on cordyceps in China, relatively little information is available from U.S.-based scientists. A few animal studies have shown cordyceps feeding to increase the ratio of adenosine triphosphate (ATP) to inorganic phosphate (Pi) in the liver by 45-55% - an effect that may be viewed as beneficial in terms of energy state and potential for performance enhancement. Furthermore, mice fed cordyceps and subjected to an extreme low oxygen environment, were able to utilize oxygen more efficiently (30-50% increase), better tolerate acidosis and hypoxia (lack of oxygen) and live 2-3 times longer than a control group. A number of Chinese clinical studies, primarily in elderly patients with fatigue, cordyceps-treated patients reported significant improvements in their level of fatigue, ability to tolerate cold temperatures, memory and cognitive capacity and sex drive. Patients with respiratory diseases also reported feeling physically stronger. Overall, the efficacy rate for cordyceps in alleviating fatigue in elderly subjects was 80-90%. In addition to its effects on energy levels – possibly due to the adenosine content of cordyceps, the mushroom extract can also induce sex steroid-like effects (in mice) – which may account for the increased libido reported by elderly subjects in several studies. Recently, a small study presented at the American College of Sports Medicine annual meeting (1999), showed that a cordyceps-based supplement (CordyMax, Pharmanex) significantly increases maximal oxygen uptake and anaerobic threshold, which may lead to improved exercise capacity and resistance to fatigue.
Safety--- Dietary supplements of Cordyceps sinensis are not associated with any significant side effects.
Value At about $25 for a 120 capsule bottle, cordyceps will cost you around a buck a day – not too bad for something that appears effective in alleviating fatigue and giving your libido a little nudge.
Dosage--- 2-4 grams per day of cordyceps sinensis has been associated with increased energy levels, reduced fatigue and an enhanced ability to use oxygen.
