Cordyceps Mushrooms For Endurance

For quite a while I have been hearing good things about cordyceps mushrooms, and specifically Cordyceps Sinensis (and the related Cordyceps Militaris) – that it can help with stamina and endurance, and can improve male sperm quality. So what is the truth?

This fungus grows on specific caterpillars in the higher mountain regions of China. Once the province of the wealthy due to its rarity, cordyceps can now be grown in the laboratory under less gruesome conditions. For this reason it is becoming more widely accepted as the price has come down to affordable levels.Cordyceps Mushrooms For Endurance

In China this prized herb has been in continous use for several centuries. In this context it has been used to warm and tonify the kidneys (with a particular action on sore lumbar back and knees) and invigorate the lung to ease breathing difficulties. It is also said to dissolve phlegm. In Tibet it is specifically used for weakness and fatigue.

Cordyceps species contains all of the essential 18 amino acids, vitamins E, K, B1, B2 and B12, polysaccharides, proteins, sterols, nucleosides, macro- and microelements (K, Na, Ca, Mg, Fe, Cu, Mn, Zn, Pi, Se, Al, Si, Ni, Sr, Ti, Cr, Ga, V and Zr).

I was particularly interested in its effect on poor sperm quality. In traditional Chinese medicine this is often attributed to a weakness of the kidneys. A trial on 90 laboratory rats given Cordyceps Militaris (American Journal of Chinese Medicine, 2008) showed a significant improvement in both sperm count and motility. Another trial published in the same journal the year before showed a similar effect in a small group of subfertile boars. Both trials suggested that the effect peaked at about 6 weeks, and lasted for at least two weeks after discontinuing the supplementation.

Other research has shown that cordyceps has very low toxicity, though its safety is unproven in pregnancy. Although I could find no formal trials of cordyceps in humans (though research does confirm other pharmalogical effects) , the research on animals seem to reinforce the sperm boosting properties traditionally attributed to Cordyceps by Traditional Chinese Medicine.

Acupuncture Dosage Explained

According to wiktionary.org the word ‘dosage’ is defined as the administration of a medication etc, in a measured amount. So what might the measured amount be in an acupuncture treatment?

Acupuncture Dosage Explained

To help answer this question I went to the checklist at STRICTA.info (which offers reporting guidelines for acupuncture researchers). According to this some of the factors that can affect treatment strength are:-

  • Number of treatment points used
  • Depth of insertion
  • Amount of stimulation applied to the needle
  • Needle retention time
  • Needle thickness
  • Total number of treatment sessions
  • Frequency of sessions
  • Style of acupuncture (eg Western medical, Chinese, Japanese, Korean)
  • Any additional interventions offered (eg cupping, moxibustion)

In my experience, one treatment is usually insufficient – a larger dose is often needed. After all, you don’t expect to take just one tablet after a visit to your GP.

In a 2008 paper, Dr. Adrian White also argued that ‘the dose may be affected by the state of the patient (eg nervous, immune and endocrine systems); different doses may be required for different conditions’. It has been argued by others that where trials have shown little or no effect over placebo, this is due to an insufficient dose of acupuncture being given.

So how do we establish the correct dose? In clinical practice, this is usually determined by experience. I would generally give a smaller dose of treatment on the first visit, and also if you have a weaker constitution. Whilst it is normal to experience a little drowsiness after an acupuncture session, extended periods of drowsiness or sleeplessness may indicate too high a treatment dose. Over treatment is usually self-resolving in a few days at most and is not generally considered a safety issue. If you experience side-effects please discuss these with your acupuncturist.

As a patient you should always ask your practitioner how many sessions are anticipated and he/she should agree one or two treatment goals at the outset (eg significantly reduce PMS symptoms). In establishing a correct dosage I usually combine clinical experience with information gained from studies.
