Therapeutic attributes of Methyl Salicylate:

The most significant qualities of Methyl Salicylate are as follows:

Analgesic:

Methyl salicylate serves as an analgesic to relieve pain in joint and muscles.  According to the study ‘Involvement of Transient Receptor Potential Vanilloid Subtype 1 in Analgesic Action of Methyl salicylate’, it was found that Methyl salicylate inhibits human transient receptor potential vanilloid subtype1 (TRVP1) and this inhibitory property of methyl salicylate may partly contribute to the analgesic effect of Methyl salicylate.

It is a counterirritant that relieves the pain by first cooling and then warming the skin. These alternate feelings divert the feeling of pain in muscles, joints and bones.

Rubefacient:

Methyl Salicylate used in the topical application is one of the medicinal rubefacient that redden the skin by dilating the blood capillaries and thus increasing the blood circulation naturally.

Anti-inflammatory:

Methyl salicylate shows anti-inflammatory activity. This is witnessed by the book ‘Aspirin and the salicylates’. When methyl salicylate cataplasm is tied to the rat paws, it produces anti-inflammatory activity existing for 72 hours after its topical application.
