About Simarouba
This bag holds only the bark of Simarouba amara, wild-harvested, then dried and ground with nothing added. It is the same bark that goes into our Simarouba Capsules and Simarouba Extract.
The ground bark has no smell, and its bitterness carries straight into the cup. Simmer it rather than steep it: a teaspoon to each cup, boiled gently in a covered pan for 20 minutes, then left to settle before you pour. More in our Simarouba herb guide.
