Harvesting and Processing Methods and Key Technical Points for Pinellia ternata
Those propagated from tubers are harvested in the same year or the following year, while those grown from seeds can only be harvested in the 3rd to 4th year. Harvesting is generally carried out in summer or autumn after the stems and leaves wither and the plants fall over. After digging them out, pack them in baskets, wash off the mud and sand while they are still fresh, put them into gunny sacks and shake off the outer skin, then pour them out and wash the outer skin clean with clean water. Scoop them out and dry them in the sun to obtain raw Pinellia ternata. Generally, the yield of fresh tubers is 500-750 kg per mu, with a drying ratio of about 30%.
