]. Ginseng is not normally prescribed for pregnant women, or for patients under the age of 40, or those with depression, acute anxiety or acute inflammatory disease[
]. It is normally only taken for a period of 3 weeks[
]. Excess can cause headaches, restlessness, raised blood pressure and other side effects, especially if it is taken with caffeine, alcohol, turnips and bitter or spicy foods[
]. The roots are harvested in the autumn, preferably from plants 6 - 7 years old, and can be used fresh or dried[

Seed - sow in a shady position in a cold frame preferably as soon as it is ripe, otherwise as soon as the seed is obtained. It can be very slow and erratic to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a shady position in the greenhouse or frame for at least their first winter. Make sure the pots are deep enough to accommodate the roots. Plant out into their permanent positions in late summer.
