- Harvest
- Autumn (September-October), 4-6 year old plants
It is harvested in autumn when the roots have stored the greatest amount of nutrients. It takes 4-6 years of growth to obtain pharmaceutical grade roots.
Root washed, cut and dried in the sun without additional processing. The soil is removed and the finest rootlets are removed.
Whole root steamed for 2-3 hours until translucent reddish in color, then dried in the sun or with gentle heat. The steam process increases the concentration of Rg ginsenosides.
Root peeled and dried directly in the sun. Less powerful than red. Can be bleached with sulfur in commercial processing (prefer unbleached).
