Safety, Side Effects and Contraindications

Lomatium dissectum can be used as a medicinal plant with potential therapeutic benefits, but its safety profile requires careful consideration.

While generally considered safe when used in recommended doses, it may cause side effects such as gastrointestinal upset, nausea, and skin irritation in some individuals. There is limited research on its interactions with other drugs or herbs, but caution is advised when combining it with anticoagulants or medications that affect the liver, as it may enhance their effects. Special populations, including pregnant or breastfeeding women and individuals with chronic illnesses, should avoid lomatium dissectum due to insufficient safety data and potential risks to fetal or infant development.

Growing, Harvesting and Storage

Lomatium dissectum grows in well-drained, sandy or loamy soils with a pH between 6.0 and 7.5, in full sun to partial shade, and requires consistent moisture during its growing season.

It thrives in cooler climates and benefits from regular watering, especially during dry periods, but should not be overwatered to avoid root rot. To maintain healthy growth, it is important to weed regularly, mulch around the base to retain moisture, and ensure good air circulation to prevent fungal diseases. Harvesting is best done in late summer to early fall when the roots are mature and the plant has accumulated maximum medicinal compounds; the roots should be carefully dug out with a garden fork to avoid damaging the plant.

After harvesting, the roots should be thoroughly dried in a well-ventilated area or using a dehydrator, then stored in airtight containers in a cool, dark, and dry place to preserve potency and extend shelf life.
