Description

The fresh or dried fruits of different Capsicum species are used medicinally. Capsicum oleoresin is prepared by extracting the crushed capsicum with volatile solvents by percolation method. Preparation made from the oleoresin in cayenne and oleoresin's isolated constituent 'Capsaicin' is used as topical analgesic in OTC (over the counter) market. The herb is indigenous to Mexico and Central America. Methyl salicylate, menthol and camphor are originally derived from plants. Methyl salicylate is derived from oil of wintergreen, menthol is derived from mint and camphor is derived from a number of plants including Peppermint, Eucalyptus and Cedar.

Pharmacology

Capsicum species are known to be very strong local stimulants in the circulatory system. Its reduction of thromboxane B2 formation and erythrocyte hemolysis suggests a membrane stabilizing property that interferes with the activation of phospholipase A2. Capsicum activates nociceptive fbres, which induces the release of excitatory neurotransmitters, bind to specific vanilloid (capsaicin) receptors and its effects are reversible. Capsicum induces selective analgesic effect by depleting substance P, a neuropeptide of 11 amino acids that mediates the transmission and modulation of pain impulses from the peripheral nerves to the spinal column. Capsicum initially stimulates substance P release from peripheral sensory C type nerve fibers, then prevents its re-uptake and also blocks its transport within the neuron, which causes its eventual depletion resulting in analgesia.

Methyl salicylic acid is similar to that of Aspirin that shows anesthetic properties by blocking the voltage-operated sodium channels in pain-receptor neurons.

Menthol molecule binds and stimulates the TRPM-8 receptor protein that produces a sensation of cold (pain in extreme cases) when stimulated.

Camphor has been approved by FDA for topical use as a pain reliever and anesthetic. It acts as counter irritant and numbs the nerve endings that inhibit the transmission of pain sensation.
