The ginseng plant requires a specific set of environmental circumstances to thrive. Most farmers prefer to grow ginseng from seeds. In a process called stratification, the farmers subject the seeds to hot and cold treatments in an environment with lots of moisture for several months. Most seeds don't germinate until after their first year. Once germination begins, any handling of the young seedling can damage the plant, leading to a loss.
Ginseng thrives best in areas of full shade and plenty of moisture. In the wild, deciduous forests with spleenwort and wild ginger indicate optimum growing conditions for ginseng. Many farmers attempt to reproduce these conditions, providing heavy organic matter in the soil and heavy shade. Aphids often present a problem, as well as rodents and root and crown rot, among other diseases. Most large-scale growers state that human theft comprises the majority of their concerns.
Under well-maintained artificial conditions, root harvest can take place in as little as four years. Wildly cultivated sites may take six years or longer depending on the weather. Harvest the roots very carefully to avoid damaging any root branches. Whole roots have higher value than pieces. Wash the roots thoroughly and dry in a heated, well-ventilated room. Once dried, the roots will store well in a dry, well-ventilated, rodent-proof container and kept just above freezing temperatures.
Ginseng has many medicinal and herbal uses. Traditionally it is used to treat diabetes, boost the reproductive drive in men and boost energy and vitality. The sliced or powdered root steeps in a tea, though the leaves may also provide the same benefits. Several energy drinks currently on the market contain ginseng as an ingredient. Side effects of an overdose may include the inability to sleep, heart palpitations and interactions with medications.
