Aidplast Perforated Cold Plaster is a therapeutic adhesive patch measuring 12cm x 18cm. It contains menthol, methyl salicylate, and camphor that work together to provide cooling relief for muscle and joint pain through its perforated design that allows skin breathability. This cold plaster utilizes menthol from mint plants to create a cooling sensation and pain relief by stimulating cold receptors and inhibiting pain signals. The methyl salicylate component provides topical pain therapy, while camphor helps with analgesic effects through receptor interaction. Together, these ingredients help dilate blood vessels and increase blood flow to the applied area. It is indicated for muscle strains, joint pain, lumbago, sciatica, and rheumatic conditions.
