From a modest grocery started in 1932, today Greater Ouiheng Group is one of the successful privately owned manufacturers and distributors of pharmaceutical products, consumer heathcare as well as develops and distributes own branded products.

Ouiheng group of company was first started in 1932 which took root from a modest grocery named "Moek Hua" founded by Mr. Lieng Tengamnuay at No. 4-6 Maharaj Road, Thaprachan, Bangkok, which name was changed a year later to "Ouiheng"

In 1937, Nr. Kian Tengamnuay, Mr. Lieng's 3rd son, had to leave school to assist his father doing business. During that period Mr. Kian's age was just only 13 years old whom later was the successor to look after the business. In 1947, ten yaers later there was a big change to the business as Mr. Kian has decided and started to turn the grocery partly into a drugstore and it was a turing point of business entering into pharmaceutical field. Under the supervision and hard working of Mr. Kian, his business has grown successfully and finally become a 100% drugstore in 1956. In the same year, Mr. Kian has decided to legally register the company under the name of "Ouiheng Co., Ltd."

Continuting and true to his father's rigid policy of honesty to customers, Mr. Kian has built up such goodwill and trust of prescribing doctors and buyers, that Ouiheng grew to be a leading drugstore and pharmcy in the area. The company started also wholesale business and in time become one of the two biggest wholesalers of pharmaceutical products in Thailand.

Due to its large sales volumes, Ouiheng has been attracted by a number of foreign manufacturer of ethical products to offer their agencies.
