From many firms adapting Thai herbalism, Harnn & Thann has spun a global chain of high performance, eco-friendly body products. Think rice bran scrubs, lemongrass aromatherapy oil and strings of multi-spice soaps. In products and in-store spas, Harnn evokes an old apothecary, Thann a swish lab chic. Thann Native also sells decor and furnishings by top Thai designers. It also runs Thann Sanctuary spas.
