What parts of this plant are used medicinally?

This plant uses both the leaves and the stems of Colquhounia vestita for various medicinal applications. The leaves are frequently harvested to create decoctions or infusions used in traditional healing practices. These leafy parts often contain specific phytochemicals that contribute to the plant's therapeutic properties. Additionally, the stems are collected and processed alongside the foliage to maximize the medicinal yield. This combined usage allows practitioners to utilize the entire aerial portion of the herb for treatment.

According to a study published by "Phytochemistry", the leaf and stem surfaces of Colquhounia vestita contain dense peltate and capitae glandular trichomes. These glandular trichomes harbor 3 diterpenoid acids, specifically one clerodane 5-epi-hardwickiic acid and 2 labdanes, which are polyalthic acid and E-communic acid. The major component identified from the peltate glandular trichomes is polyalthic acid. Under UV radiation and cold stresses, this polyalthic acid helps the plant adapt to abiotic challenges.
