It may interact with certain drugs, including sedatives and anticonvulsants, potentially increasing their effects or causing adverse reactions.

Growing, Harvesting and Storage

Pinellia ternata grows in moist, well-drained soils that are rich in organic matter, typically in shaded or semi-shaded areas with partial sunlight, making it suitable for cultivation in forested regions or under the canopy of trees.

It thrives in temperate climates with consistent moisture levels, requiring regular watering but avoiding waterlogging to prevent root rot. For optimal growth, the soil should be loamy or sandy-loam with a pH between 5.5 and 7.0, and the plant benefits from mulching to retain soil moisture and suppress weeds. Harvesting is best done in late summer to early autumn when the leaves begin to yellow, using a sharp knife to cut the rhizomes cleanly from the plant, ensuring minimal damage to the roots.

After harvesting, the rhizomes should be thoroughly washed, sliced, and dried in a well-ventilated area or using a dehydrator to preserve their potency, then stored in airtight containers in a cool, dry place to maintain their medicinal properties.
