Lomatium Root (Lomatium dissectum) is one of the most robust of the desert parsley and is harvested mainly for its strong antiviral properties but is also an effective immune enhancer. Harvesting Lomatium root can be a challenge not only because of the size of the root but that is likes to grow on steep rocky hillsides. We must also take care not to damage the root during the digging process so that the oily constituents are not lost. I have seen this root take over an hour to harvest with to people digging diligently. Also, harvesting roots now, in the fall is optimum since the leafy part of the plant has died off and the medicines in the root are at their strongest.
The fresh root is cut to expose the oily constituents to the solvent (food grade alcohol) that over a six week period will transform into a strong antiviral medicine. The alcohol will then be strained and bottled and usually blended with other tinctures such as Arrowleaf Balsamroot and Elderberry for their immune enhancing qualities.
