The Formula for Pain: A Topical That Cools and Warms at Once
By Dr. Shanna Hudgin

Most topical rubs pick a lane. They're either cooling — heavy menthol, sharp, good for something freshly inflamed — or warming, built on ginger and cinnamon-family herbs for the stiff, achy, worse-in-January complaints.
The Formula for Pain does both deliberately, and that combination is more useful than it sounds.
What's in it
A topical herbal cream from Lhasa, part of the Peekay's line, combining traditional Chinese herbs with a modern cream base. The formula is built on hong hua and hua jiao, alongside menthol, camphor, and essential oils of cajeput, ginger, and peppermint. It's silky and fast-absorbing rather than greasy.
Two of those are worth knowing by name:
Hong hua — safflower — is one of the most recognizable herbs in the Chinese blood-moving category. It appears throughout the traditional trauma and pain literature, and it's a standard component of liniments and plasters.
Hua jiao — Sichuan pepper — is a warming herb with a distinctive tingling quality. If you've eaten Sichuan food and felt your lips buzz, that's the same botanical. In topical use that quality is the point.
Why cooling and warming together
This is the genuinely interesting part of the formulation.
Menthol and camphor produce an immediate cooling sensation — the counter-irritant effect behind nearly every sports rub on the shelf. Ginger, cajeput and hua jiao work in the opposite direction, producing warmth that comes up more slowly and lasts longer.
The traditional logic for combining them is that most real-world aches aren't purely one thing. A low back that's stiff every morning but flares hot after a heavy day has both a chronic cold-and-stuck component and an acute irritated one. A single-direction topical addresses half of it.
Practically, most people notice the cool first and the warmth a minute or two later. If you've used Evil Bone Water (cooling, alcohol-based, evaporates fast) and Battle Balm Demon Strength (warming, rich, stays put), this sits between them — cream texture, both sensations, absorbs quickly enough to dress afterward.
Who reaches for it
The people who come through our door with working bodies: trades and construction, nurses on their feet all day, lifters, weekend athletes, and anyone who spent Saturday on a ladder. It's also a reasonable choice for people who find straight menthol products too sharp, since the warming side softens that edge.
How to use it
Apply to the area and work it in. Wash your hands afterward — hua jiao and ginger in your eyes is a memorable mistake. Don't use it on broken skin or open wounds, and don't pair it with a heating pad; menthol-containing topicals plus applied heat can irritate or burn skin. Patch test first if your skin is reactive, since warming botanicals are a common source of irritation.
The limit worth naming
A topical changes how an area feels for a few hours. It does not change why the area feels that way.
That's fine for a rough week. It's a signal worth acting on if you're reaching for it every morning on the same shoulder or the same segment of low back. At that point the cream has become a way of tolerating a mechanical problem rather than solving it, and a real structural exam is the higher-value move. Our Gonstead chiropractic guide walks through the five-pillar analysis we use to find which segment is actually generating the problem — which, as often as not, isn't the spot that hurts.
Get evaluated promptly for pain following significant trauma, inability to bear weight, numbness or tingling, weakness, or a joint that's visibly unstable.
