For generation, Siang Pure products have been the treatment trusted by Thais and valued for its many herbs, prescribed by ancient Chinese formulas. Siang Pure Products are Thailand's market leader in ointment products.

     Beginning as a small family enterprise, Bertram Chemical has advanced in a matter of decades to a place of prominence in the Asian market, selling to the Chinese People's Republic, the United Arab Emirates, Malaysia, Singapore, Vietnam, Cambodia and many countries in Europe and Americas.

     Only recently has the world become aware that Nature is a storehouse of long-term aids to this planet's ecological and physical health. Drugs derived from Nature are now important parts of alternative medicine, combining the strengths of both the modern and traditional healing arts.

     At Bertram Chemical, traditional medicine has always been the basis of our philosophy. We have long believed that natural treatments are the most suitable to human health needs, and recent studies have proved us right.
