Plant by Plant

Calendula flowers carry a compound called faradiol monoester, and in tests on lab animals it was the compound most responsible for the flower's anti-inflammatory effect on skin. Lemon balm leaves carry rosmarinic acid, which in a test tube blocked part of the activity of an enzyme that breaks down GABA, a brain chemical that quiets nerve signals. Each article here covers a single plant at that level of detail: what the plant is, which compounds are in it, what researchers tested, and what they found, with every paper listed at the bottom so you can read it yourself. When one of my KBA & Co guides covers the plant in more depth, the article names the guide and links to it.
