This is a shrub (fig. 430) growing freely in many parts of North America. From the flowers and dried bark are made the medicinal preparations in use. These are extract, powder, distilled extract, and ointment.
For haemorrhage, witch-hazel is used both as an external application and an inward remedy. It is applied as a lotion to arrest bleeding from wounds, and given for haemorrhage from the lungs and abdominal organs. For piles in young foals it is an excellent remedy, and is employed both topically and internally. The dry extract, which has not been officially recognized in the Pharmacopoeia, makes an excellent ointment for soft granulating wounds with a tendency to bleed. The dilute lotion is sometimes applied to inflamed eyes.
