|Germination||In general, this plant is common in the wild. It is in great demand for medicinal use, so it is cultivated on farms in India, but most plant material sold into the pharmaceutical trade comes from wild populations. This is one reason for its decline in parts of its native range. In Sri Lanka it has become rare, and in Orissa it is thought to be nearing extinction. On the other hand, it has been introduced outside its native range and has become a weed which may be invasive. In Australia, for example, it now can be found growing in coastal areas of Queensland and New South Wales. It also is cited as an invasive species in the Cook Islands, French Polynesia, Kiribati, and Singapore.
The plant can be propagated sexually by seed or vegetatively by dividing the rhizome. Problems during cultivation include inadequate pollination, fungal diseases such as leaf blight and tuber rot, and crop pests such as the moths Polytela gloriosa and Chrysodeixis chalcites. It is also a crop that is slow to propagate; each split tuber produces only one extra plant in a year's time. In vitro experiments with plant tissue culture have been performed, and some increased the yield.
Both the fruit and the rhizome are harvested. The fruits are dried and split, and the seeds are removed and dried further. The seeds and rhizomes are sold whole, as powder, or as oil extracts.
