Throughout history humans have found a way to condense the active components in bulk herbs into herbal extracts. We have infused them in oil, simmered and decocted them in water, cold-percolated them and macerated them in alcohol to form a tincture. The following products are quite concentrated and most of the medicinal constituents of the plant are extracted with minimal processing. They are readily absorbed into the body where they are fast acting and efficacious.
