Yohimbe interacts negatively with many prescription medications, including those used for depression, blood pressure, diabetes, and allergies.

Coltsfoot is a plant in the sunflower family and is also known as coughwort. The extract of this sunny yellow herb is used for inflammation, respiratory problems, and as an antiseptic. While coltsfoot may be effective for these conditions, the pyrrolizidine alkaloids it contains are highly toxic to humans. These alkaloids are metabolized in the body to form products which destroy the liver.
