Safety, Side Effects and Contraindications

Lepidium sativum can be considered generally safe when used in recommended doses for short-term purposes, though it may cause mild gastrointestinal side effects such as nausea, diarrhea, or abdominal cramps in some individuals.

It is important to note that there is limited clinical data on long-term use, and potential interactions with certain medications, including anticoagulants and antidiabetic drugs, may occur, although research in this area is sparse. Pregnant and breastfeeding women should avoid lepidium sativum due to insufficient evidence regarding its safety during these periods, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is advisable to start with low doses, monitor for adverse reactions, and consult with a qualified healthcare professional, especially if taking other medications or supplements.

Growing, Harvesting and Storage

Lepidium sativum grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, in full sun to partial shade, and requires regular watering to maintain consistent moisture without waterlogging.

It thrives in cool climates and is typically planted in early spring after the last frost, with seeds sown about 1/4 inch deep and spaced 6 to 8 inches apart to allow adequate growth. Regular weeding and thinning of seedlings are essential, and mulching helps retain soil moisture and suppress weeds. Harvesting occurs when the plant reaches maturity, usually 45 to 60 days after sowing, by cutting the stems just above the soil level to avoid damaging the roots.

For optimal potency, the harvested plant should be dried in a shaded, well-ventilated area or in a dehydrator at low temperatures, then stored in airtight containers in a cool, dark place to preserve its medicinal properties.
