Professional Skin Care & Beauty Since 1999
Tranquil Siam is a London-based wellness brand founded by Sutthida, who grew up surrounded by traditional herbal medicine in Khon Kaen, Northern Thailand. After moving abroad and finding the international market flooded with low-quality imitations of Thai herbal products, she partnered directly with licensed manufacturers in Thailand to bring authentic, certified herbal remedies to a global audience. The result is a curated range of herbal teas, traditional Thai balms, and botanical supplements — each produced under Thai FDA registration, independently lab-tested for purity, and made exclusively from certified organic ingredients with no synthetic additives, fillers, or steroids.
What distinguishes Tranquil Siam from the crowded wellness market is the direct sourcing model. There are no middlemen, no grey-market intermediaries, and no mystery blends. Every product is traceable to its origin in Northern Thailand, where herbs are cultivated in the region's mineral-rich soils and processed using traditional low-temperature drying methods that preserve the full spectrum of beneficial plant compounds. Independent third-party laboratory testing confirms the absence of steroids and contaminants in every batch — a critical assurance in a category where adulteration has been a documented problem.
Tapee Tea (also known as Tepee or Thephi Tea) is Tranquil Siam's bestselling product and the centerpiece of their collection. It is a traditional Thai herbal infusion containing 15 carefully selected organic botanicals, handcrafted in small batches in Northern Thailand. The blend is based on a revered recipe that has been trusted across generations in Thai herbal medicine, and the official English name registered with the Thai FDA is "Thephi Herbal Drink."
The primary ingredient is Jewel Vine (Derris scandens), comprising 65% of the blend. This creeping leguminous plant native to Southeast Asia contains the flavonoid antioxidant derridin and has been used for centuries in traditional Thai medicine. The remaining 35% is composed of fourteen complementary botanicals: Star Anise for digestive support and its characteristic licorice-like aroma; Ceylon Cinnamon rich in proanthocyanidin antioxidants; Nutmeg for its calming, aromatic properties; Thai Black Galangal (Kaempferia parviflora), prized in Thailand as an energizing herb; Turmeric with its well-documented curcumin content; Astragalus root, an adaptogen used for immune balance and stress resilience; Bael Fruit from the Ayurvedic tradition; Brazilwood (Caesalpinia sappan), which gives the tea its distinctive ruby color; Licorice root for natural sweetness and soothing properties; Siamese Cardamom with its cooling menthol notes; Dang Shen (Salvia miltiorrhiza) for circulatory support; Makiang (Cleistocalyx nervosum) with its floral aroma and antioxidant tannins; Chaplu leaf adding a peppery bite; and Clove for warming, eugenol-rich depth.
Each 3-gram sachet is designed to be steeped in 250–350 ml of freshly boiled water for 3–5 minutes. The tea is naturally caffeine-free, making it suitable for any time of day, and can be enjoyed hot or served chilled over ice. It is available in both sachet and tea-bag formats, with pricing from US$24.99 for a single pack up to US$343.99 for bulk quantities of 20 packs.
Every batch of Tranquil Siam's products undergoes testing by an independent, accredited third-party laboratory. Certificates of Analysis confirm purity, the absence of steroids and synthetic additives, and compliance with the manufacturer's Thai FDA registration. The company also offers steroid testing kits so customers can independently verify product purity — a level of transparency that is rare in the herbal supplement industry. All ingredients are certified organic, grown without pesticides or chemical fertilizers, and harvested using sustainable practices that Tranquil Siam's founder has personally vetted through direct visits to the partner farms in Northern Thailand.
Beyond Tapee Tea, Tranquil Siam offers a broader collection of Thai herbal teas including detox blends, jiaogulan (Southern Ginseng) tea, butterfly pea flower tea, and lemongrass infusions — each formulated around the principles of traditional Thai herbal medicine, where multiple complementary botanicals work synergistically rather than relying on a single active ingredient. The range also includes traditional Thai herbal balms for topical use and botanical supplements, all held to the same sourcing and testing standards as the flagship tea.
Tranquil Siam ships worldwide to over 50 countries with free standard international shipping on all orders. Delivery typically takes 7–14 business days from their fulfilment centre in Thailand, with full tracking provided. All purchases are backed by a 30-day money-back guarantee.
Skin1's curation philosophy has always been to identify brands that combine proven ingredients with genuine expertise and transparent quality standards — whether that means Obagi's medical-grade formulations developed with dermatologists, Dr. Hauschka's biodynamic approach to holistic skincare, or Yon-Ka's five-decade heritage in aromatherapy and phytotherapy. Tranquil Siam belongs in this company because it applies the same principles to Thai herbal wellness: authentic formulations rooted in centuries of traditional knowledge, certified organic ingredients with documented provenance, and rigorous independent testing that goes beyond industry norms. For customers who have embraced the natural and botanical end of skincare through brands like Dr. Hauschka, Yon-Ka, and 100% Pure, Tranquil Siam extends that philosophy into ingestible herbal wellness — the idea that what you put into your body matters as much as what you put on your skin.
