This is a great supplement. It is often combined with wormwood and clove for use against parasites and candida. Today I bought just the walnut hull extract, alcohol free in coconut glycerine. This stuff is great. I worry about the toxicity of wormwood, so wormwood should only be used for short periods of time. Black walnut green hull extract seems like it is safe enough for longer term use.

Besides being antifungal and antiparasitic, black walnut green hull extract halps thyroid problems, especially low thyroid output, and various skin problems(chronic skin infection, ringworm, etc.)
