You can get it from the "Adhivasi" tribe areas esp. in Vayanad, Kerala, Ayurvedic institutes, or Govt. Herbs Nursery homes. You can grow it at your place which depends on well-caring of the plant, the type of soil, light, rain, etc...

In the late 1980s, Indian scientists stumbled on a plant called aarogyapacha, used by Kani tribals of Kerala to fight fatigue. Based on Kani knowledge, they developed a restorative, immuno-enhancing, anti-stress and anti-fatigue agent drug called Jeevani. The technology to manufacture the drug was licensed to Arya Vaidya Pharmacy Ltd (avp), and benefits from sales were to be shared with the Kani.
Then the deal floundered. The Kerala forest department refused permission to the Kani to either cultivate or collect the aarogyapacha plant, and sell it as a raw material to avp. It even turned down an offer by avp to pay the Kani initial seed money for cultivation, and enter into a buy-back arrangement for five tonnes of leaves a month. The department's reason? Aarogyapacha was an endemic plant.
U MAY BETTER TRY YOUR LUCK WITH kERALA FOREST DEPARTMENT for the seedlings.. Best of luck kovai
