Medical Condition	Uses based on scientific evidence	Grade*
other disorders of ear	calendula has been studied for reducing pain caused by ear infections. some human studies suggest that calendula may possess mild anesthetic (pain-relieving) properties equal to those of similar non-herbal eardrop preparations. further studies are needed before a recommendation can be made in this area.	c
posttraumatic wound infection not elsewhere classified	calendula is commonly used on the skin to treat minor skin wounds. reliable human research is necessary before a firm conclusion can be drawn.	c
unspecified local infection of skin and subcutaneous tissue	limited animal research suggests that calendula extracts may reduce inflammation when applied to the skin. human studies are lacking in this area.	c
varicose veins of lower extremities with ulcer	calendula has been suggested as a possible treatment for venous leg ulcers. further study is warranted.	c
