ABOUT ALEVEX
AleveX is a line of topical pain relievers - and expansion of the well-known oral naproxen sodium-based line called Aleve. Its parent company is Bayer, which produces an impressive number of medical and agricultural products globally.
ALEVEX ACTIVE INGREDIENTS
CAMPHOR This waxy solid has a strong aromatic odor. It is found in the wood of the evergreen tree Cinnamomum camphora; Dryobalanops aromatica; Ocotea usambarensis; and dried rosemary leaves (Rosmarinus officinalis).
It is a large contributor to the product's scent, but it is also easily absorbed through skin and produces a cool-feeling like menthol.
MENTHOL
Speaking of menthol, this organic compound is made synthetically or obtained from mint oils.
Menthol stimulates the transient receptor potential channel melastatin 8 (TRPM8). This receptor is responsible for the well-known cooling sensation it provokes when inhaled, eaten, or applied to the skin.
Menthol also has weak analgesic (pain-killing) effects due to select activation of the κ-opioid receptor. This receptor is a protein that mediates a variety of effects including changing our perception of pain, consciousness, motor control, and mood.
ALEVEX SIDE EFFECTS
There are no known major side effects for using Alevex topically (on the skin, external use only). Although one should seek medical attention if severe allergic reaction occurs. Not a good idea to use on broken or damaged skin, and be sure to keep it clear of the eyes - ouch.
SUMMARY
I found an established body of research that may suggest the use of menthol for mild pain relief. Given the very low risk and very limited side effects, it would seem worth a try for individuals seeking a complementary and/or off-the-shelf product for pain relief.
You can purchase Alevex at most major pharmacies.
