What does it do?

L-menthol is primarily used as an antispasmodic agent for the relief of muscle spasms or pain. It is also utilized for skin irritation relief and topical analgesia.

When L-menthol comes into contact with the skin or mucous membranes, it produces a cooling sensation that reduces pain and relieves muscle tension. This is due to its action of stimulating nerve receptors to inhibit the transmission of pain signals.

Approved uses differ by product. Check each product's information for its actual use.
