8) Our Verdict on Barberry Root Bark

Barberry Root Bark is an herbal extract sold in bulk. It should be of good quality according to the distributor which emphasizes that it sells either organic or wild-harvested plants. However, we have not found online client reviews therefore we cannot say much about customer satisfaction. The extract is imported and in our view, some clients might prefer barberry grown in the US.

We recommend you ask for advice from a specialist if you are planning to make barberry based formulations as this herb interacts with a lot of drugs, so it would be better to know exactly just how much to include in your formulations in order to avoid serious side effects.
