Traditional calming mushroom with very little human mood evidence and a liver caution.
This is information, not medical advice. This page is information, not medical advice. Nothing here is a prescription, a diagnosis or a recommendation to take anything, and none of it replaces a doctor who knows your history. Supplements are not harmless because they are natural: they interact with prescription medicines, some are unsafe in pregnancy, and a few can cause real damage. Talk to a doctor or pharmacist before starting anything here, especially if you are pregnant, breastfeeding, under 18, have a liver, kidney or heart condition, or take any regular medication. Never stop a prescribed antidepressant to try a supplement instead.
A hard, bitter mushroom used in Chinese medicine, sold as extract for stress, sleep and immunity.
Human trials are few and mostly concern fatigue in illness rather than anxiety in general, with modest and inconsistent results. The traditional reputation is long; the modern evidence for mood is close to absent.
Studies used roughly 1.5 to 5 g daily of extract.
Recorded because a person who has decided to try something will find a number somewhere, and a forum's number is worse than a trial's. It is not a recommendation, and the right amount for you depends on things only a doctor who knows your history can weigh.
Cases of liver injury have been reported, particularly with powdered products. Can thin the blood - care with warfarin and before surgery. May lower blood pressure and blood sugar. Avoid in pregnancy.
Imported, and sold at a considerable premium for what the evidence supports.
Tell your doctor or pharmacist about everything else you take, prescription and herbal both. If you are pregnant, breastfeeding, under 18, or have a liver, kidney, heart or thyroid condition, ask first. And if what brought you here is that you have been feeling low or frightened for weeks, that deserves more than a supplement — ask us anything, anonymously, or talk to us on WhatsApp.
