A number of plant drugs are used in topical application meant for medical and cosmetic purposes. Many of such recommended drugs have been reported to cause contact dermatitis which fact is well supported by clinical studies. To find out the role of these plant drugs in the etiology of contact dermatitis, clinical studies of 34 such herbal drugs were carried out.
