Bangkok Balm Natural Herbal Gel Products

Bangkok Balm makes two clinically distinct herbal gels,
each formulated by Numchai 'Chai' Lertvechakul — an Agro-Industrial Product Development graduate of Kasetsart University and the son of a traditional Chinese medicine practitioner. Unlike conventional oil-based balms that sit on the skin's surface, both Bangkok Balm products use a proprietary gel base that absorbs rapidly, leaving no greasy residue and no fabric staining. 

Both products are registered with the Thai Food and Drug Administration (Thai FDA), independently tested by Central Laboratory (Thailand) Co., Ltd. — a testing agency initiated by the Thai government — and sourced exclusively from GAP-certified farms
in Northern Thailand.

Bangkok Balm Organic Acanthaceae Herbal Gel

For skin relief: insect bites, heat rash, itching, and allergic skin irritations.

The Primary Ingredient: Clinacanthus nutans (Slaed Phang Phon)

The active ingredient in Bangkok Balm Organic Acanthaceae Herbal Gel is an extract of Clinacanthus nutans — known in Thai as Slaed Phang Phon — a flowering plant native to Southeast Asia and a cornerstone ingredient in traditional Thai herbal medicine.

Clinacanthus nutans is recognised in traditional Thai medicine for its anti-inflammatory and anti-viral properties, making it particularly effective for skin conditions involving irritation, swelling, and allergic reaction.

What Makes This Formulation Effective: The Extraction Method

Bangkok Balm uses a fresh-leaf aqueous extraction method — processing the plant immediately after harvest using water as the solvent rather than heat or chemical solvents. This approach preserves the natural enzymes and bioactive compounds in Clinacanthus nutans that are responsible for its therapeutic effect.

The extract is then formulated into Bangkok Balm's proprietary gel base — a water-based, non-greasy carrier that allows the active compounds to penetrate the skin quickly rather than sitting on the surface as oil-based balms do.

What It Treats

  • Insect bites — reduces swelling, redness, and itching on contact

  • Heat rash (prickly heat) — soothes irritated skin in tropical conditions

  • Itching from skin allergies and contact irritants

  • General allergic skin reactions and minor inflammations

Bangkok Balm Organic Plai Muscle Gel

For muscle and joint relief: aches, post-workout soreness, tension, and inflammation.

The Primary Ingredient: Zingiber montanum (Plai)

The active ingredient in Bangkok Balm Organic Plai Muscle Gel is a high-concentration extract of Zingiber montanum — commonly known as Plai — a species of ginger native to Southeast Asia and one of the most widely used medicinal plants in Traditional Thai Medicine (TTM).

Plai's therapeutic value comes from its naturally high concentration of terpinen-4-ol — a naturally occurring compound recognised for its analgesic (pain-relieving) and anti-inflammatory properties. Applied topically, terpinen-4-ol helps reduce localised swelling, ease muscle tension, and support circulation in the treated area.

What Makes This Formulation Effective: The Extraction Method

Bangkok Balm uses a proprietary cool-process extraction for the Plai extract. Processing at low temperatures preserves the integrity of terpinen-4-ol and other heat-sensitive bioactive compounds in Zingiber montanum that degrade under conventional high-heat extraction methods.

As with the Acanthaceae Gel, the Plai extract is delivered in a fast-absorbing, non-greasy gel base — meaning it will not stain training gear, sportswear, or bed linen.

What It Treats

  • Muscle aches and post-exercise soreness

  • Sports and training recovery (Muay Thai, running, gym)

  • Tension in the neck, shoulders, and back

  • Painful or stiff joints

  • Localised inflammation from overuse or minor injury

  • Primary Extract: Zingiber montanum (Plai) — cool-process high-concentration extract

    Full Ingredient List: Zingiber montanum extract, Proprietary Gel Base

    Extract Source: GAP-certified farms, Northern Thailand

    Extraction Type: Proprietary cool-process (low-temperature, to preserve terpinen-4-ol integrity)

Quality, Safety & Sourcing

Bangkok Balm sources both Clinacanthus nutans and Zingiber montanum exclusively from farms in Pichit, Thailand that carry
|Good Agricultural Practices (GAP) certification. GAP certification
— overseen by the Thai Department of Agriculture — verifies that herbs are grown, harvested, handled, and stored under documented safety and quality standards, with no prohibited pesticide or chemical residues.

By sourcing locally from certified farmers, Bangkok Balm supports sustainable Thai agriculture while ensuring full traceability from field to formula.

Frequently Asked Questions About Bangkok Balm

  • The key difference is the formulation format. Most traditional Thai balms are oil- or wax-based — they sit on the skin's surface, feel greasy to the touch, and are known to stain clothing. Bangkok Balm uses a water-based proprietary gel that absorbs into the skin rapidly. This means no residue on hands or clothes, no sticky feeling after application, and faster delivery of the active herbal compounds to the tissue where they're needed. The formulation also avoids the strong camphor smell associated with traditional balms — making it comfortable for daily use in workplaces, public transport, or shared spaces.

  • Yes. Bangkok Balm Organic Acanthaceae Herbal Gel was originally formulated by Chai Lertvechakul specifically for his young child's sensitive skin—and was rigorously tested on over 500 volunteers before its commercial launch in 2011.

    Both products are registered with the Thai FDA and are crafted with natural, high-quality ingredients. The Acanthaceae Gel is steroid-free and paraben-free, making it an ideal choice for sensitive and young skin.

    For Children (Ages 3+): While our formula is gentle, we recommend it for children above 3 years old. To ensure total comfort:

    • Apply a small amount to the crook of the arm (inner elbow).

    • Wait a few moments to test for sensitivity before applying to larger areas.

  • Yes. The Organic Acanthaceae Herbal Gel was developed specifically for sensitive skin — the formula is steroid-free and paraben-free, and is independently tested by Central Laboratory (Thailand). If you have a known allergy to any listed ingredient, we recommend a patch test on a small area of skin before full application. For severe skin conditions, consult a dermatologist before use.

  • Yes. Because Bangkok Balm is a gel rather than an oil or wax-based balm, it absorbs quickly into the skin without leaving a greasy layer on the surface. You can apply either product and dress immediately — it will not stain clothing, sportswear, or bed linen. This is one of the most practical differences from traditional Thai balms, which are known to leave residue on fabric.

  • For optimal results, apply a thin layer to the affected area 2 to 3 times daily, or as needed. Gently massage the gel into the skin until fully absorbed. Both formulas are gentle enough for frequent daily use. Avoid applying to broken, open, or severely irritated skin.

  • Do not apply Bangkok Balm to open wounds, broken skin, or eyes. If irritation occurs, discontinue use.  

  • Bangkok Balm sources both Clinacanthus nutans and Zingiber montanum from GAP-certified (Good Agricultural Practices) farmers in Pichit Province, Thailand. GAP certification ensures that herbs are grown, harvested, and handled under documented safety standards with no prohibited agrochemical residues. Local sourcing supports Thai agricultural communities and allows Bangkok Balm to maintain direct quality oversight from farm to formula.

  • All Bangkok Balm products are independently tested by Central Laboratory (Thailand) Co., Ltd. — a testing and certification agency established with Thai government backing to verify product safety for both local and export markets. Both products are registered with the Thai Food and Drug Administration (Thai FDA): Acanthaceae Gel (G470/65) and Plai Muscle Gel (G400/65).

  • Bangkok Balm is available at trusted pharmacies and health stores across Thailand, including Phetcharat Pharmacy (Siriraj and Ngamwongwan branches) and Bai Miang Health Stores (multiple locations — see the Bai Miang store locator). For online orders within Thailand, Bangkok Balm is sold through the official U-Thong Shop on Shopee and Lazada, and via the Vitaman Shop on Shopee. Always purchase from authorised sellers to ensure product authenticity.

  • Yes. Bangkok Balm is currently available in Singapore and Malaysia through Great Natural Taste Malaysia, and through authorised resellers in Hong Kong and Taiwan. Bangkok Balm is currently undergoing ASEAN GMP certification with the intention of entering UAE and European markets by late 2026.
