Cordyceps side effects

For many decades now, Cordyceps have proven to be difficult to obtain. Whilst being expensive and not widely used, wild Cordyceps are pretty difficult to come by.   Fortunately, however, scientists have figured out how to manage Cordyceps spores in a laboratory which in turn makes them much more widely available to the public. Supplements are commonly found in most health food stores at more affordable prices at the same time as appearing to offer the same benefits as the wild varieties.  A further advantage of growing controlled species of Cordyceps is the ability to control contamination, such as harmful bacteria and heavy metals. However, there can be side effects from Cordyceps for some people who have pre-conditions.

Side effects and interactions

Cordyceps are considered safe for most people but there are, inevitably, some potential side effects to be aware of. Especially for pregnant women and those with a history of auto-immune diseases.  Pregnant or breastfeeding women would be well-advised to avoid taking Cordyceps. This is because their safety hasn’t been well-researched or confirmed for this population.

For those with a known auto-immune disease (e.g. Lupus, Rheumatoid Arthritis or Multiple Sclerosis) some doctors warn that Cordyceps might exacerbate the problem.  Cordyceps ability to stimulate the immune system could mean it’s possible that usage could interfere with medications for these diseases.  Usage could also over activate certain immune cells.  The same warning goes for anyone with a bleeding or blood clot disorder,  since medical mushrooms can sometimes interfere with proper blood clotting.

It’s now possible to purchase Cordyceps tablets, powders and capsules from most health food stores and over the internet.  Many people prefer to take them orally and others even like to open the capsules and use the powder in teas, soups and stews.  This is, in fact, how they were traditionally taken in China for hundreds of years.

Dosage depends upon the reason that they are being used. The recommended amount is approximately 5 to 10 grams of Cordyceps once or twice per day.  You should follow the dosage advice on the product label or speak with a herbalist about treating a specific condition. You don’t necessarily need to take them every day if you’re only trying to prevent future illnesses and boost your immune system. In that case once or twice a week with a lower dose works well.

Please ask your healthcare professional for advice if on medication to understand possible Cordyceps side effects.
