White Flower Oil (Pak Fah Yeow): Complete Guide
White Flower Oil — known in Cantonese as Pak Fah Yeow (白花油) — is one of the most recognisable medicated oils in East and Southeast Asia. For generations, families across Hong Kong, Singapore, Malaysia, and the Chinese diaspora worldwide have kept a small bottle in the medicine cabinet for everything from headaches to motion sickness to mosquito bites. If you grew up in a Cantonese household, chances are you know its distinctive cool, faintly floral scent by heart.
This guide covers everything you need to know: the history behind the product, what’s actually in it, what it’s good for, how it stacks up against Tiger Balm, and where you can buy it if you’re outside Asia.
A Brief History
White Flower Oil was developed in the early twentieth century and is produced by Hoe Hin Pak Fah Yeow Manufactory, a company with roots in the southern Chinese merchant tradition. The formula draws on traditional Cantonese folk medicine — the kind of aromatic oil remedy that herbalists and travelling tradespeople carried for common ailments on long journeys.
The product gained widespread popularity throughout Southeast Asia during the colonial era, distributed alongside other proprietary remedies like Tiger Balm (produced by the rival Bayer family of Penang). In Hong Kong, it became firmly embedded in everyday household culture, sold in pharmacies alongside soy sauce and rice wine in the kind of all-purpose sundry shops that once lined every high street.
Today, Hoe Hin continues to produce White Flower Oil in Singapore. The product is sold across Asia and exported globally, with a particularly strong following among overseas Chinese communities.
What’s In It?
White Flower Oil is an all-natural formula comprising several plant-derived essential oils suspended in a paraffin oil base. The key active ingredients are:
- Lavender Oil (~40%) — the dominant ingredient, providing mild analgesic and calming properties
- Eucalyptus Oil — decongestant and anti-inflammatory; responsible for the menthol-adjacent freshness
- Menthol (from Peppermint Oil) — produces the characteristic cooling sensation on skin contact; activates TRPM8 cold receptors
- Methyl Salicylate (Wintergreen Oil) — a topical analgesic related to aspirin; helps with deeper muscle and joint discomfort
- Paraffin Oil — the carrier base, allowing the active oils to spread evenly and penetrate skin
The result is a lighter, more floral-medicinal scent compared to the sharper, camphor-heavy smell of Tiger Balm. Many people who find Tiger Balm too pungent prefer White Flower Oil for this reason.
What Is It Used For?
Headaches and Migraines (Mild)
The most iconic use. Apply 1–2 drops to the fingertips and massage gently into the temples and forehead. The menthol cooling effect creates a counter-irritant sensation that helps distract from pain signals, while the massage promotes local blood circulation. Best for tension headaches caused by fatigue, stress, or screen time.
Motion Sickness
Applied to the philtrum (the groove below the nose), behind the ears, or on the inner wrists before or during travel. The aromatic inhalation helps settle nausea. A practical, non-drowsy option for those who can’t tolerate antihistamine tablets.
Insect Bites and Minor Itching
The cooling menthol provides immediate itch relief. Apply directly to the bite. It won’t reduce swelling as effectively as a topical hydrocortisone cream, but it’s fast-acting and widely available.
Muscle Aches and Stiffness
Massage into sore neck, shoulder, or lower back muscles after prolonged sitting or exercise. The methyl salicylate component penetrates more deeply than menthol alone, making it useful for mild muscular tension — though not a substitute for proper treatment of sports injuries.
Nasal Congestion
Apply a tiny amount to the sides of the nostrils (not inside) or simply inhale from the bottle. The eucalyptus and menthol vapours temporarily open the airways. Useful for mild colds or hay fever.
White Flower Oil vs Tiger Balm: What’s the Difference?
| Feature | White Flower Oil | Tiger Balm White |
|---|---|---|
| Form | Liquid oil | Balm/ointment |
| Dominant scent | Floral, cool (lavender + menthol) | Sharp, camphor-forward |
| Key ingredients | Lavender, eucalyptus, menthol, methyl salicylate | Camphor, menthol, cajuput, clove |
| Camphor content | None | Yes — a key ingredient |
| Best for | Headaches, motion sickness, bites | Muscle pain, headaches, congestion |
| Texture on skin | Light, absorbs quickly | Greasy residue, longer application |
| G6PD risk | Moderate (menthol, methyl salicylate) | High (camphor) |
| Office-friendly? | Yes — scent is mild | Less so — scent is strong |
Neither is objectively better. Many Asian households keep both. Tiger Balm tends to win for deep muscle soreness; White Flower Oil is preferred for headaches and situations where you need something discrete.
Safety Considerations
- Not for oral use. The essential oil concentrations are too high to ingest safely.
- Keep away from children under 2. Menthol and camphor-based products can cause breathing difficulties in infants. White Flower Oil does not contain camphor, but the menthol concentration is still inappropriate for very young children.
- G6PD deficiency (Favism). Menthol and methyl salicylate may pose oxidative stress risks for people with G6PD deficiency, a genetic condition more prevalent in Southeast Asian, African, and Mediterranean populations. Consult a doctor before use. See our dedicated guide: Medicated Oils and G6PD Deficiency.
- Pregnancy. Consult your doctor before using any essential oil product during pregnancy.
- Avoid eyes and broken skin. If contact occurs, rinse immediately with water.
- Flammable. Keep away from open flames.
Where to Buy White Flower Oil Outside Asia
See our full guide: Where to Buy Asian Medicated Oils Outside Asia. In brief:
- Amazon (US/UK/Germany) — usually stocked by third-party Asian grocers, check reviews for authenticity
- iHerb — carries White Flower Oil with reliable international shipping
- YesStyle — ships widely from Hong Kong, good for multipacks

Authentic White Flower Oil is produced by Hoe Hin and comes in a distinctive small glass bottle with a green-and-white label. Be cautious of unlabelled imitations sold in tourist markets.
Final Verdict
White Flower Oil is not a cure for anything, but as a fast-acting, natural comfort remedy for headaches, queasiness, and minor aches, it earns its place in the medicine box. Its light scent, liquid formula, and small bottle make it practical for travel, office drawers, and handbags. If you’re new to Asian medicated oils and want to start somewhere gentle, this is a sensible first choice.
As with all topical remedies, it’s an aid — not a substitute for medical treatment when symptoms are persistent or severe.
