Folk have been rubbing mint on themselves for ages. Chinese herbalists call it bo he, and it got its entry in the Tang government's big book of medicines in 659 (yes, they had one). The ancient Greeks were fans as well. Nobody knew why it felt cold, they just liked it.
Our peppermint's a mongrel, really, watermint crossed with spearmint, and an English naturalist wrote it up in 1696. Then Mitcham happened. If you'd walked through that bit of Surrey in the 1800s you'd have smelt the fields before you saw them. Menthol, the cold bit, had already been got out as crystals in the late 1700s.
Eucalyptus came later, from Australia, where Joseph Bosisto started distilling the oil commercially in the 1850s. Put menthol and eucalyptus together and you've got the smell of every changing room in the country. Biofrost adds MSM, a sulphur compound, to the mix.
The science bit
Here's the clever bit. Menthol doesn't actually cool your skin down much at all. It switches on the same nerve receptors that respond to cold (scientists call them TRPM8), so your brain gets the message 'brr' while the temperature barely moves. Your nerves get fooled, that's all.
Eucalyptus brings that changing-room whiff and peppermint sharpens it up. The gel's gone in a minute or two, no greasy patch on your shirt. We find the cold creeps up for a bit after you've rubbed it in, then levels off.
Chinese medicine has its own way of talking about this. Mint is classed as cool and pungent, a herb that 'disperses'. So while Biofrost isn't a traditional formula, the cool-mint idea is one herbalists would recognise straight away.
How it's used
Where people tend to reach for a cooling gel. We're describing habits and rituals here, not making medical claims.
A cold rub on the legs after a run or a long day on your feet is a bit of a ritual for lots of people.
Some of our customers just like the fresh feeling on a sticky afternoon. Fair enough.
No mess, no oily hands. You can put it on and pull your sleeve straight back down.
Cold gel at lunch, warm oil at bedtime. A few of you do exactly this, we've noticed.
Biofrost Cool Gel is a cooling gel for external use. It isn't a medicine and isn't meant to diagnose, treat or prevent any condition.
Inside the bottle · Ingredients
We've listed the headline ingredients here. For every last one, have a look at the bottle.
The cooling bit
Menthol does the heavy lifting. Peppermint and eucalyptus are mostly there for the smell, if we're honest.
Also in the gel
MSM. Short for methylsulfonylmethane, which nobody says out loud. It's a sulphur compound you'll spot on lots of sports gel labels.
How to take
Squeeze out a little and spread it thinly over the area. A thick blob just takes longer to dry.
Massage gently until it's all absorbed, then wash your hands.
You can reapply as you like, up to four times in a day.
External use only. Patch test first, skip broken skin, keep it well away from your eyes, and don't cover it with a heat pad or a tight bandage.

Nope! Stick a thermometer on it and you'd barely see a change. The menthol's just tickling your cold sensors, and they're very easily fooled.
Up to four times a day. Thin layer, rub it in till it's gone.
It's a clear gel and dries quickly, so it shouldn't. Give it a minute to sink in before you get dressed, though.
Please don't. Menthol rubs and heat pads, hot water bottles or tight wraps aren't a good mix, as the skin can get irritated or even burnt.
Skin only, never broken skin, and keep your fingers out of your eyes afterwards (ouch). Not one for babies or small kids either, menthol and eucalyptus are too much for them. If you're expecting, breastfeeding or on regular meds, ask your GP or pharmacist first, they won't mind.
Bit like asking tea or coffee. Biofrost's the cold, in-and-out one. Hysan smells of cinnamon and wants you to sit down and take your time.
