Herbs in Oral Mucositis.

Oral mucositis is an inflammatory mucosal destruction as a result of chemotherapy and/or radiation therapy, which in severe cases can impair patients' quality of life. Moreover, mucosal infection and/or systemic involvement due to compromised immunity leads to delay or discontinuation of the treatment. Many strategies and agents have been suggested for the management of this condition.
