If you've already heard of Hong Thai, you probably know that it's a natural inhaler that has been gaining increasing popularity recently. People today are leaning more towards natural alternatives to traditional medications, and Hong Thai is one of those alternatives. But did you know that there are several different types of Hong Thai? Let’s take a look at the different types of Hong Thai available on the market and which one is the best for you!
Hong Thai is a traditional Thai herbal inhaler filled with dried herbs soaked in menthol, camphor, borneol and eucalyptus oil. If you want to know what it is, how it works and how to use it, read our main guide What is Hong Thai. In this article we focus on one thing only: the differences between the individual variants, so you can pick the right one.
Hong Thai variants compared
The main Hong Thai types differ in the colour of the packaging, the blend of herbs and how strong the scent is. Here is a quick overview:
| Variant | Key ingredients | Scent | Intensity | Best for |
|---|---|---|---|---|
| Green (original, Formula 2) | Menthol, camphor, borneol, eucalyptus oil | Sharp, cooling menthol | High | Daily carry, office use, driving, blocked nose |
| Yellow (Traditional 15 Herbs) | 15 Thai herbs with camphor, eucalyptus and menthol | Deeper, softer and more herbal | Medium | Relaxation, meditation and focus |
| White (Borneol) | Menthol, borneol, camphor and herbs | Very strong and penetrating | Very high | Intensive refresh, heavy colds, headaches and sinus pressure |
Hong Thai green (original Formula 2)
The green variant of Hong Thai is considered the classic version. This inhaler is known for its ability to relieve stress and tension, relax the body, and improve mood. The composition includes:
- Menthol: Has a refreshing and cooling effect that helps relieve fatigue and stress. It relaxes the airways and provides immediate relief during a cold.
- Borneol: This ingredient is known for its calming effects on the nervous system. It helps with relaxation and improving concentration, which is ideal for calming the mind.
- Camphor: Camphor helps relax the airways and has analgesic effects. It is effective for relieving headaches and a blocked nose.
- Eucalyptus oil: Eucalyptus is known for its ability to clear nasal passages and support breathing.
The green Hong Thai jar is an icon, but it is not the only option worth knowing. Our guide to Hong Thai vs. Poy Sian vs. Hanuman puts all three side by side so you can see where each one fits.
Hong Thai yellow (Traditional 15 Herbs)
The yellow variant is popular for its relaxing effects and is ideal for improving concentration and mental well-being. Its composition includes a blend of various herbs soaked in essential oils with camphor, eucalyptus, and menthol as key ingredients.
Unlike the green inhaler, which relies on intense menthol, the yellow version focuses on the depth and balance of fifteen Thai herbs. The scent is softer and more herbal, which suits people who find the green one too sharp. You can find it in our shop as the Hong Thai Yellow herbal inhaler.
Hong Thai white (Borneol)
The white variant is intended for intensive relief from respiratory problems and stress. It is suitable for people suffering from frequent headaches or migraines. It contains a combination of medicinal herbs like the already mentioned borneol, camphor, eucalyptus oil, and also contains mint flakes to relieve tension and other healing herbs.
Hong Thai Formula 1 vs Formula 2
Many people search for the difference between Hong Thai Formula 1 and Formula 2. Formula 2 is the name printed on the classic green Hong Thai bottle, the original herbal inhaler with menthol, camphor, borneol and eucalyptus oil that you will find in most shops today.
Formula 1 is rarely sold outside Thailand and the manufacturer does not publish a detailed comparison of the two. If you come across it, check the composition on the label. If you want the classic that made Hong Thai famous, choose the green Hong Thai herbal inhaler.
How to get the most out of your Hong Thai
Many people encountering Hong Thai for the first time are unsure how to handle this traditional pot. It’s not a balm or a liquid drop. Inside the plastic container, you’ll find a blend of 15 types of dried herbs wrapped in a fine gauze and saturated with essential oils.
-
The proper technique: Unscrew the cap and hold the jar close to your nose. Take a deep breath. For maximum relaxation, inhale slowly and let the aromatic compounds work on your senses.
-
Activating the blend: If you feel the scent is fading over time, simply close the jar and give it a firm shake. This redistributes the essential oils from the bottom back to the herbs on top.
-
Lifespan: With daily use and proper sealing after each sniff, one inhaler will stay potent for 3 to 6 months.
Which Hong Thai is the best?
If you’re deciding which Hong Thai inhaler is right for you, it depends on the effects you expect from it. Each variant has its own specific properties, but if you’re looking for a universal option that provides quick relief and is ideal for daily use, then the green Hong Thai is the best choice, and we recommend choosing the gold or, in this case, the classic green variant.
If you’re looking for a natural way to relieve stress, improve concentration, or relieve a blocked nose, Hong Thai inhalers are a great choice. Whether you choose the green, yellow, or white inhaler, each has its specific effects that can provide quick relief and improve comfort.
