What's Inside PainGo? How Menthol, Wintergreen, Capsicum and Eugenol Work Together

When you rub PainGo into a sore shoulder, you feel two things at once: a fresh coolness, then a gentle, spreading warmth. That isn't an accident. PainGo combines four ingredients that each play a different role, and understanding them helps you get the most out of every application.

Menthol (1%): the cooling touch

Menthol comes from mint oils. It activates the skin's cold-sensing receptors, which is why it feels cool without actually lowering your temperature. That cooling sensation acts as a counterirritant: it gives your nerves something new to focus on, which can take the edge off an ache. It's the reason menthol is found in so many sports rubs and balms.

Wintergreen oil (0.1%): the classic muscle-rub ingredient

Wintergreen oil is rich in methyl salicylate, a compound related to aspirin. It has long been used in muscle and joint rubs for its soothing, warming effect on stiff, overworked areas.

Capsicum (0.05%): the gentle warmth

Capsicum comes from chilli peppers and contains capsaicin, which activates the skin's heat-sensing receptors. The result is a comforting warmth that builds slowly. With regular use, capsaicin is also known to reduce how strongly nerves send pain signals from the area.

Eugenol (0.02%): nature's soothing agent

Eugenol is the main compound in clove oil, traditionally used for its soothing and numbing properties. It rounds out the formula with a mild calming effect.

Why cooling and warming together?

Cold and heat each help in different situations. Cooling can calm a fresh ache, while warmth helps loosen stiff muscles. Having both in one balm means one jar covers everything from a stiff neck after a long day at the desk to sore knees after a walk.

How to use it well

• Take a small amount with clean, dry fingertips.
• Massage into the painful area in slow circles for 1–2 minutes until absorbed.
• Use up to 3 times a day.
• Wash your hands afterwards, and keep them away from your eyes.

A few safety notes

• For external use only. Don't apply to broken, irritated or freshly shaved skin.
• Don't cover with a heating pad or tight bandage right after applying.
• Because wintergreen contains a salicylate, check with a doctor first if you're allergic to aspirin, take blood thinners, are pregnant, or are buying for a child.
• Stop using it if you notice redness or irritation, and see a doctor if pain continues.
