Traditional Chinese medicine may be the latest sector to benefit from cosmic farming as 150 grams of space-exposed ginseng seeds were delivered to a State lab on Friday.

"We hope the space ginseng will be bigger, more resistant to disease and have increased medicinal potency," said Zhou Hua, professor of Macau University of Science and Technology, the State's top research laboratory in Chinese medicines.

Ginseng has long been used in traditional Chinese medicine to enhance immunity, lower blood sugar and combat cancer.

The ginseng seeds spent 15 days in space aboard Shenzhou X in June and may take as many as six generations on the ground to show the enhanced characteristics.

Generally, it takes at least five years for ginseng plants to mature.

"Thirty years will be too long for us, so we will nurture the ginseng with a tissue culture technique to shorten the process," Zhou said, without revealing further details.

Although it is the first time ginseng has been sent to space, China has sent vegetable seeds and many traditional Chinese medicine ingredients since the 1980s.

During early experiments, Jiang Xingcun, a scientist at the Chinese Academy of Sciences, discovered that spaceflight can increase mutation rates by a hundred times over what is experienced on Earth.
