Happy Noz is a Thai onion-oil sticker you put on clothing, not on skin, so a child breathes the scent without anything touching the face. Every colour starts from the same onion base. The colour tells you which extra oil the maker has added: tea tree in blue, turmeric in green, ginger in yellow, clove in orange. Purple is the original, and Bug Guard is a separate mosquito sticker.
Happy Noz is searched around 320 times a month in Singapore, mostly by parents trying to work out which box to buy. It is also the line childcare centres and family pharmacies order from us in the largest volumes, and "which colour?" is the question we are asked most. Here is the full answer.
What Happy Noz is
Happy Noz is made in Thailand. The maker describes it as built on a selected red onion variety rich in quercetin, blended with essential oils. The onion scent is the traditional part. A cut onion by the bed is an old folk remedy for a blocked nose, and the sticker is a tidier way of doing the same thing.
The important difference from a Thai inhaler is where it goes. A menthol or camphor inhaler is not suitable for young children. A Happy Noz sticker sits on a collar, a pillow or the side of a cot, so the child gets the scent without handling anything or having a strong product near the face.
Every colour, explained
| Colour | Added oil | What the maker adds it for |
|---|---|---|
| Purple (Original) | Onion oil with eucalyptus, peppermint and lavender | Everyday blocked or runny nose |
| Blue | Tea tree oil | Against bacteria |
| Green | Turmeric oil | Against viruses |
| Yellow | Ginger oil | To soothe coughs |
| Orange | Clove oil | Haze and PM2.5 days |
| Bug Guard | Not a nasal sticker | A separate mosquito-repellent sticker |
Purple: the original
The one to start with. It is the plain onion formula with eucalyptus, peppermint and lavender, for a stuffy or runny nose. If you only buy one box, buy this.
Blue: tea tree
Adds tea tree oil, which the maker includes for its antibacterial reputation. Some parents reach for blue when a cold has moved on and the mucus has turned thick and yellow.
Green: turmeric
Adds turmeric oil, which the maker positions against viruses. It is the colour parents tend to pick at the start of a cold going round the class.
Yellow: ginger
Adds ginger oil, which the maker includes to soothe coughs. The one for a child who is coughing at night rather than just congested.
Orange: clove, for haze
Adds clove oil, which the maker includes for PM2.5 pollution. In Singapore that makes it the seasonal one, bought when the haze comes back.
Bug Guard: a different product
Bug Guard is not an onion nasal sticker at all. It is a mosquito-repellent sticker from the same company, with a cartoon frog on the pack. Do not buy it expecting help with a blocked nose. For mosquito protection on skin, a DEET spray such as SOFFELL is the stronger option.
How to use a Happy Noz sticker
- Peel one sticker. One at a time is enough.
- Stick it on clothing, at the collar or on the chest, or on a pillowcase or the side of a cot. Not directly on skin.
- Place it out of reach of a baby's hands, so it cannot be pulled off and put in the mouth.
- Replace it with a fresh one when the scent has faded.
A sticker is small enough to be a choking hazard, so supervise young children and put it somewhere they cannot reach. Check the age guidance printed on the box, and speak to a doctor if a baby's breathing seems laboured, if there is a fever, or if symptoms last more than a few days. A sticker is a comfort, not a treatment.
Happy Noz vs a Thai inhaler
They are for different people. A Thai inhaler, the yadom, is menthol and camphor that an adult holds under the nose; it should not be used on children under two. Happy Noz is onion-based, goes on clothing, and is made with children in mind. Many families keep both: the inhaler for the adults, the sticker for the kids. For adults who prefer a sticker, the maker also sells an adult range.
Buying Happy Noz for a centre or shop
Happy Noz is our largest institutional line. Childcare centres, clinics and paediatric pharmacies buy it by the box, which is also how it is sold on our Happy Noz wholesale page. All six variants can be mixed in one order. It sits on the Thai inhaler range page too, for shops comparing it with the menthol inhalers.
