If you're a Yadom fan, read on to the end.
What Is a Yadom?
Yadom is a Thai word meaning "sniffing medicine" — a stick-shaped aromatic inhaler. Inhaling its menthol and aromatic scent through the nose helps fight drowsiness and refresh the mind, and it has been beloved in Thailand for decades.
Before diving into Poy Sian, let's start with the basics: what exactly is a Yadom?
In Thai, "Yadom" combines "ya" (medicine/herb) and "dom" (to smell/inhale) — literally, a "sniffing medicine."
You inhale through your nose from a stick-shaped device, taking in the menthol and aromatic scent. It's been a beloved product in Thailand for years, known for fighting drowsiness and refreshing the mind.
In Thailand, it's not unusual to spot locals with a Yadom pressed to their nostril. The concept has also gained attention in Japanese media, so some of you may already be familiar with it.
Next, let's take a closer look at Poy Sian — the world's number-one Yadom brand.

Poy Sian Products: What They Offer
Poy Sian's flagship product, the "POY-SIAN Mark 2 Inhaler," can be used from the top for nasal inhalation and from the bottom as a mint mask applicator — a versatile, dual-function must-have. Available on Rakuten and other online retailers.
Here's an introduction to Poy Sian Yadom products available for purchase in Japan.
The most popular Poy Sian Yadom is the "POY-SIAN Mark 2 Inhaler."
The stick can be split into two sections for different uses: the upper section lets you inhale directly through the nose to enjoy the menthol scent, while the lower section dispenses mint liquid that you can dab onto a mask — making it work as a refreshing mint mask.
It's available on Rakuten and other online retailers.
Poy Sian also offers Yadom-inspired lifestyle items. One example is a reed diffuser-style product: a container filled with cotton soaked in mint oil, so you can enjoy the minty fragrance anytime, anywhere.
This item is also available on Rakuten, so check it out if it catches your interest.
