Yes. The main contraindication is active digestive disorders although this is not always the case. One Health Concerns subscriber, who is a practitioner with Crohn’s disease,has found our protocols work really well for her. Previously, she tried Western medicine protocols, which made her sick. She’s found that Cordyceps PS is best thing for her fatigue related to Crohn’s. This is just one example of someone with a digestive disorder than can take cordyceps. However, some cannot. Someone with an active diagnosis and active symptoms should have their digestive issues addressed first using different protocols. Once they are mostly healthy, or their digestive system is healthy, you can begin using Cordyceps PS or CordySeng, which you may have to modify with Quiet Digestion or Enteromend to make the cordyceps more tolerable. If the patient has a background of digestive disorders, I would tend to use CordySeng whenever possible as it contains complimentary herbs like ginger and licorice, which help with digestive aspects.
