For every ache, insect bite or itch, we Filipinos have an array of oils and balms that we swear by. Most people have a tube or tiny bottle of this wonder liniment handy just in case they feel unwell. Even Filipino-American comedian Jo Koy shared anecdotes of his mom using Vicks VapoRub to “cure” him whenever he got sick. Efficascent Oil, White Flower and Vicks are just some of these treatments that we whip out at the first hint of a headache or cold. In this article, we will be focusing on Katinko, one of the most popular camphor-menthol-salicylate balms Filipinos use.
What Is Katinko and What Are Its Uses?
A news report revealed that many people use this liniment to soothe aches and itches as well and ease nausea. On the packaging label, it’s indicated for neck and shoulder stiffness, rheumatism, muscle strain, sprains, bruises, and itching due to insect bites and other minor skin irritation. However, you should not use it on wounds, damaged skin, on or near the eyes.
Katinko contains menthol (7.6%), camphor (11%), and methyl salicylate (13%). Each one is a topical analgesic; that is, substances you apply to the skin which have painkilling properties. Let’s explore each one.
Menthol
One component of Katinko is menthol, which has analgesic effects. One study of menthol effects on migraines showed that it reduced the intensity of headaches two hours after applying topical menthol 6% gel. When administered inside the body, it blocks the nervous system’s calcium-sodium channels and desensitizes pain receptors. The cooling sensation that we know menthol gives is a result of transient receptor potential melastatin-8 channels being activated. This also contributes to the analgesic effect.
Methyl Salicylate
Another element in the composition of Katinko is methyl salicylate. The contents of fragrances, food, beverages and liniments often include this substance. In liniments, they serve as rubefacients, or drugs that cause reddening of the skin due to increased blood flow. Rubefacients are thought to ease pain in different musculoskeletal conditions; however, there’s not enough evidence to support this claim.
Methyl salicylate acts as a painkiller in deep heating liniments. This is useful for people with arthritis, simple back aches, bruises, cramps, muscle strains or sprains. Ointments containing this substance also counteract irritants.
