Cultivation and Harvesting

White Dead-Nettle is typically cultivated in temperate climates and thrives in well-drained, loamy soil with a slightly acidic to neutral pH.

It prefers partial to full shade but can tolerate some sunlight. Regular watering is necessary to maintain moist soil, though it should not be waterlogged. Propagation is usually done through seeds sown in early spring or by dividing established plants in early spring or fall. The plant matures in about 80 to 100 days, with the best harvest time occurring when the leaves are fully developed but before flowering.

Harvesting is best done by cutting the stems just above the ground level to encourage regrowth.

Processing and Extraction

The processing and extraction of White Dead-Nettle involve several key steps to prepare the plant for use in herbal medicine.

Drying is typically done by spreading the harvested leaves and flowers in a well-ventilated area or using a dehydrator to preserve the active compounds.
