neem oil

Neem oil contains a chemical known as nimbidin that gives it a sulfur-like odor and some ability to help control fungus and also work as a pesticide. Neem oil can be a skin irritant and is also poisonous if ingested—avoid this form and note that the constituents that make the oil a problem for skin aren’t present in the extracts, which is why the extracts are rated differently.
