Joint and muscle pain comes in many forms and can strike anywhere. Maybe you worked out too hard at the gym and now you can barely move your legs. Maybe you fell asleep in a chair and woke up today with a stiff neck. Maybe you forgot to lift with your legs when you rearranged the furniture, and now you feel like you can barely straighten up your back. Maybe you ignored your arthritis, decided to knit those baby booties anyway, and now your knuckles are aching worse than they have in weeks. Whatever the cause of your pain, you want relief. You don’t want to wait half an hour or more. You want relief now. Biofreeze can help.
Biofreeze is a topical analgesic. The active ingredient is menthol, nature’s tried and true pain reliever. Menthol is a naturally occurring organic compound extracted from the mint plant. It’s the same ingredient found in cough drops. Its soothing property comes from its ability to stimulate cold receptors in the skin. It doesn’t actually change the temperature of the skin. It just tricks the skin cells into sending more cold sensations to the brain than warm ones. Pain and inflammation are associated with warm sensations, so replacing them with cold ones is how menthol relieves pain. It works in much the same way as ice, except that ice actually changes skin temperature whereas menthol just changes the sensation of skin temperature. (more…)
