Certifications for medicinal plants farming

I own a piece of land with water facility.planning to start a business model medicinal farming along with other 5 investors (not farmers).what are the relevant certifications needed to start ?

Crude medicinal herbs market is very volatile , competitive and dominated by traders based in different markets i.e Amritsar, Bengaluru, Chennai, Dehradun, Delhi, Jaipur, Kolkata, Lucknow, Mumbai and Neemuch . Previously Ministry of Ayush and apex body National Medicinal plant Board(NMPB) introduced ( GAP ) Good Agricultural Practices for Producers ( Good Field collection Practices ( GFCP ) for wild collectors in crude medicinal plants category in association with Quality council of India(QCI) as certification body . It was Voluntary Certification scheme for medicinal plant produce (VCSMPP). For manufacturers GMP ( Good Manufacturing Practices ) is applicable .
A centralized with GAP / GFCP and GMP unit will help you start you new journey .
But , please make a market survery first , which medicinal; herb will be your USP first .
We used to be in wild medicinal herbs collection and trading ( Gurmar / Gymnema sylvestre ) but wind up it as manufacturers wants low priced crude products and traders wants best quality at lowest price .

Thana for the suggestion sir
