Biodynamic agriculture uses a series of preparations numbered from 500 to 508 which are based on various mineral, plant, and animal substances. These enhance all the bacterial, fungal and mineral processes that are found in the organic farming system.

There is always the question the world over, "Should we not use indigenous plants for making the preparations and not exotic plants from northern hemisphere?" I (Peter Proctor) would agree that we should but, then that question is answered by another, "Which ones?"

I do not doubt that there are indigenous plants in every region of the world that would have the right characteristics, but to get the desired influences, with regard to the enhancement of the mineral processes or the influences of the related planets, will take much observational study. So until the time comes when substitute plants are found to be effective, we must continue to use those herbal plants that have been making quality preparations for many years.

There are obvious exceptions, in India, using an indigenous oak tree in the Himalayan foot\hills, Quercus glauca, the bark of which has a high percentage of calcium, and there always seems to be indigenous perennial nettles (Urtica species) growing in most countries, that have the same qualities as that of the European nettle Urtica dioica. Urtica parviflora is the nettle growing in the Himalayan foothills.

In the hot countries it is difficult to grow the temperate climate herbs and in India we are growing them in the cooler climate of the hills. In the hill stations of the south at 2000 metres around Kodaikanal and in the foothills of the Himalayas in areas such as Nainital and Darjeeling at 1500 and 2000 metres respectively.
