The leaves and flowering tops are antispasmodic, disinfectant, emmenagogue, stimulant and vermifuge. Cotton lavender is rarely used medicinally, though it is sometimes used internally as a vermifuge for children and to treat poor digestion and menstrual problems. When finely ground and applied to insect stings or bites, the plant will immediately ease the pain. Applied to surface wounds, it will hasten the healing process by encouraging the formation of scar tissue. The leaves and flowering stems are harvested in the summer and dried for later use.
