Capsaicin comes from chilli peppers and, applied repeatedly, depletes the chemical that nerve endings use to signal pain. Menthol gives an immediate cooling sensation that distracts from pain. Together they are the basis of many rubs, gels and patches.

What Capsaicin and Menthol Products Are Used For

Muscle aches, sprains and strains
Joint pain, including osteoarthritis of the knee
Back and neck pain
Nerve pain, with regular use over weeks

Common Side Effects

Burning, warmth or stinging where applied
Redness of the skin
Coughing or sneezing if the vapour is inhaled

Precautions

The burning sensation is expected and eases with continued use over the first days. Wash your hands thoroughly afterwards and never touch the eyes, nose or genitals before doing so. Do not apply to broken skin, and do not use a heating pad or hot shower straight after, as that can cause a real burn. Stop if blistering or severe pain occurs.
