Safety, Side Effects and Contraindications

Lithospermum erythrorhizon can be used with caution due to its potential for adverse effects and interactions.

It may cause gastrointestinal upset, allergic reactions, and in some cases, hemolytic anemia due to its active compound, shikonin. It should be avoided during pregnancy and breastfeeding as it may pose risks to fetal development and infant health. Patients with chronic illnesses, particularly those affecting the liver or kidneys, should consult a healthcare provider before use, as the herb may interact with medications such as anticoagulants or immunosuppressants.

To ensure safe use, it is recommended to follow a healthcare professional's guidance, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Lithospermum erythrorhizon grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires consistent moisture without waterlogging.

It thrives in temperate climates and should be planted in spring after the last frost, with rows spaced 30-45 cm apart to allow for adequate air circulation. Regular weeding and mulching help control weeds and retain soil moisture, while pruning dead or diseased foliage promotes healthy growth and prevents disease spread. Harvesting should occur in late summer to early autumn when the roots are most potent, using a sharp spade to carefully dig up the entire plant, ensuring minimal damage to the roots.

After harvesting, the roots should be washed, dried in a shaded, well-ventilated area, and stored in airtight containers in a cool, dark place to preserve their medicinal potency and extend shelf life.
