Lab studies show Tiger Milk Mushroom has anticoagulant & fibrinolytic actions (both increase risk of bleeding) - so must be cautious in ppl who take blood thinner. But no human study done, so we don't know what dose will cause that.
Licorice (high dose) - known to reduce the effect of warfarin (blood thinning drug), but the dose in TMK is low.
Also, these effects of TMM and licorice are opposite. Hopefully they cancel out.
Can take at recommended dosage - not to exceed 1 sachet daily.
