Red clover is a useful internal and external remedy for skin complaints such as psoriasis or eczema. It is also a good expectorant and is used for whooping cough, bronchitis, dry coughs, and laryngitis. Red clover is sometimes taken as an anticancer remedy. The herb is a component of the well-known formula, "Red Clover Compound," of which there are a number of variations that are commercially available. In addition to red clover, these formulas usually contain burdock root or seed, echinacea, sarsaparilla, and other "blood purifying" herbs. This formula is often recommended by western herbalists as an adjunct to a comprehensive cancer preventative treatment program.
