Trichostema lanatum, the woolly bluecurls,[1] is a small evergreen shrub or sub-shrub native to arid coastal chaparral regions of California and the northern parts of Baja California.

Trichostema lanatum is many-branched and grows to 1.5 m (5 ft) tall, with narrow, pointed green leaves. The smooth-petaled blue flowers are borne in dense clusters, with the stem and calyces covered in woolly hairs of blue, pink, or white. Flowers are present from March to June.[2]

Spanish explorers in California called the plant romero, the Spanish term for rosemary, and that common name is still sometimes used.[3]

Uses

Trichostema lanatum is cultivated as an ornamental plant, and several cultivars have been developed.[3] It attracts hummingbirds and bumblebees.[4]

It is aromatic and glandular. Native Americans used it for a variety of medicinal and other purposes.[5]

It makes a flavorful tea.[3]

Indigenous Medicinal Uses

Woolly bluecurls (Trichostema lanatum) was incorporated by the Chumash to help facilitate the healing process of menstruation and birth.[6] When tested against an E.Coli ▵tolC mutant, woolly bluecurls (Trichostema lanatum) exhibited anti-bacterial properties.[7][8] Studies have also shown anti-inflammatory properties against pro-inflammatory cytokine TNF-ɑ and anti-bacterial properties against macrophages and gram-postivie bacteria, corresponding with the use of woolly bluecurls (Trichostema lanatum) as a disinfectant and treatment for rheumatism by the Chumash peoples of California.[9]

Trichostema lanceolatum was used by California Indigenous tribes in the form of tea or crushed leaves to treat a range of ailments including common olds, body aches, skin disorders, digestive problems, and malaria.[10] Trichostema lanceolatum and Trichostema lanatum are both a part of the Lamiaceae family. They differ in smell, smell, and location found.[11][12] Indigenous tribes used Trichostema lanatum to treat the same ailments as Trichostema lanceolatum.[10] Woolly bluecurls (Trichostema lanatum) and other native plants have historically been used by Indigenous peoples in a holistic approach to medical care, which typically considers patient health and well-being at the intersection of biology, psychology, and culture, and manipulating the biochemical properties of native plants to treat the ailment.[13]

Future studies of woolly bluecurls and other plants used by Indigenous peoples for medicinal purposes will need to focus on the use of such plants in a broader cultural system of care. Such work can be challenging, given the historical, systematic erasure of Indigenous wisdom that has been a primary function of settler colonialism.
