Stherb Cosmetics Company is registered in Thailand. Our company's main efficacy is pueraria mirifica and butea superba. These 2 herbs are used to make all of our products, therefore, to differentiate us from other pueraria mirifica suppliers, we requested a test from CTFA on our quality of pueraria mirifica and butea superba. It was approved and our company becomes and still remains as the only pueraria mirifica and butea superba supplier approved. This ensure the efficiency of our products which are made by the highest quality pueraria mirifica and butea superba found in the world. We have our own bioengineer farm for growing the herbs that are quality controlled to give the best efficacy. Therefore, no other supplier can achieve what our products can do. Because we are still selling very well worldwide.
