Lomatium dissectum

Lomatium dissectum, also known as Biscuitroot, is a hardy North American herb with a history of food and medicinal use. While Indigenous peoples traditionally roasted its taproot for sustenance, modern herbalists value it as a powerful respiratory and immune ally. It works by helping to clear congestion and stimulating the body's natural defense mechanisms. It is a potent alternative to more common herbs like Echinacea, particularly for stubborn seasonal respiratory issues.

Deep Dive

Lomatium dissectum contains a rich profile of essential oils, coumarins, and resinous acids. These compounds are responsible for its 'heating' and drying nature in herbal medicine. It is particularly indicated for respiratory infections that seem to linger, characterized by heavy congestion. Unlike simple Vitamin C, Lomatium appears to have a direct action on the respiratory mucous membranes, helping to dry up secretions and resolve the infection. It is often used in formulas alongside other herbs like Licorice root and Boneset.

Natural Food Sources

Lomatium is not a 'nutrient' found in everyday fruits and vegetables. It is a specific botanical root. Historically, the root was eaten as a survival food.

Supplementation

Because the fresh root is difficult to source and has a strong flavor, most users rely on:

Tinctures (Liquid Extracts): The most bioavailable form.
Dried Root Tea: Steep 1-2 tsp of dried root in hot water for 10-15 mins.
Capsules: Dried root powder.

Frequently Asked Questions

The root has a strong, resinous, and slightly bitter taste with a licorice-like undertone. It is quite strong, which is why many prefer capsules over the liquid extract.
