Wise advice.Deer tongue is a blood thinner. People who take prescription blood thinners should probably avoid it. Those who have any health problems might want to check with their doctor. It might be well to use it sparingly, since dose is significant. Just a note of caution.
When I read the word coumarin I wondered if it was the same thing as my blood thinning meds.
Yep, it is.
Not sure if it would have a similar effect smoking coumarin as digesting but it's definitely worth investigating before using Deer Tongue.
It's why I'm soaking vanilla beans in 13yo spiced rum as using Deer Tongue is not worth the risk without knowing it's effect for certain.
