What is Ya Khiao Bai Pho?

Ya Khiao Bai Pho is a traditional Thai herbal medicine — a long-standing household remedy made by the Bai Pho pharmacy house (registration no. G18/36). It is a "Ya Khiao" (green medicine) formula combining several cooling herbs, available as tablets and as powder.

The principle of Ya Khiao is to use cooling herbs to "reduce heat" in the body. In Thai traditional medicine, an excess of internal heat causes fever, a hot body, internal heat, and thirst — Ya Khiao helps rebalance and relieve these symptoms. It belongs to the same family as "Ya Khiao Hom," a formula included in Thailand's National List of Essential Medicines.

Benefits of Ya Khiao Bai Pho

The stated benefits of Ya Khiao Bai Pho are to relieve fever, a hot body, internal heat, thirst, measles and chickenpox rashes. In summary:

  • Reduces fever and body heat: eases general fever, especially from hot weather or mild inflammation
  • Relieves internal heat and thirst: soothes mouth heat, canker sores, dry throat and thirst
  • Brings out the fever rash: in Thai tradition, it helps the rash of measles and chickenpox emerge fully and quickly
  • Rebalances body heat: used on hot days or when feeling drained by heat

Ya Khiao is a symptomatic herbal remedy in Thai traditional medicine — it is not an antibiotic and does not kill germs directly. If fever is high or infection is suspected, see a doctor as well.

How Ya Khiao Relieves Internal Heat and Mouth Sores

"Ron nai" (internal heat) is a familiar complaint in Thailand — usually mouth ulcers (aphthous ulcers), dry cracked lips, dry throat, or a burning-hot feeling in the body. Thai traditional medicine views it as an imbalance of excess internal heat.

Ya Khiao uses cooling herbs to help lower internal heat, ease mouth heat and thirst, and refresh the body. A Thai study has evaluated Ya Khiao Hom powder for the care of aphthous ulcers, reflecting its long-standing use.

Ya Khiao for Fever with Rash, Chickenpox and Measles

In Thai traditional medicine, Ya Khiao is often used for febrile rash illnesses in children such as measles, chickenpox and rubella — believed to help "draw out the fever toxin" so the rash emerges quickly and fully, while easing fever and body heat as the rash appears.

However, measles and chickenpox are viral illnesses. The mainstay of care is rest, plenty of fluids, fever control, and watching for complications. Ya Khiao is a complementary practice from Thai wisdom and does not replace medical treatment. If a child has a high fever, is drowsy, will not drink, or the rash becomes infected, see a doctor immediately.

Can Children and Pets Take Ya Khiao Bai Pho?

Children: Ya Khiao Bai Pho is suitable for both adults and children, with children taking a smaller dose (1-5 tablets by age and weight). Dissolve it in water for easy dosing and ensure plenty of fluids. For very young children or those with underlying conditions, consult a pharmacist first.

Pets: There is a folk practice of giving Ya Khiao to pets with fever or suspected distemper (e.g. dogs, cats), but giving human medicine to animals carries risks because dosing and responses differ. Always consult a veterinarian first — do not self-medicate pets without professional advice.

Side Effects and Precautions

Ya Khiao Bai Pho is a herbal remedy generally safe at recommended doses, but note these precautions:

  • Herbal allergy: rare, but if rash, itching, or swelling occurs after taking it, stop and consult a pharmacist
  • High fever or fever over 2 days: do not rely on Ya Khiao alone — see a doctor to find the cause
  • Pregnant and breastfeeding women: consult a doctor or pharmacist before use
  • People with chronic conditions or on other medicines: tell your pharmacist to avoid interactions
  • Keep out of reach of children and store in a dry place away from moisture

Ya Khiao is for initial symptom relief, not a treatment for infections. If symptoms are severe or do not improve, always see a doctor.

Ya Khiao Tablets vs Powder

Ya Khiao Bai Pho comes in two main forms — choose by convenience:

  • Tablets: easy to measure and carry; count tablets by the recommended dose (adults 7-10, children 1-5), usually dissolved in water first
  • Powder (sachets): the traditional form, dissolves easily, ideal for children or anyone who finds tablets hard to swallow, with adjustable amounts

Both forms have the same herbs and benefits — they differ only in convenience. Intimo Life offers both single-unit and pack options.
