Clinical Information

Patients have described Woolly Blue Curls as “romantic, enticing, uplifting, and aphrodisiac.” Traditional teas and hydrosols are used like chamomile for stomachache and fevers. Historically, Chumash healers employed infusions to expel the afterbirth, while Spanish Californians used decoctions for colds, flu, and bruises.

Traditional & Modern Preparations

• Tea (Infusion) — 1–2 g dried flowering tops steeped 5–10 minutes. Taken in ½–1 cup servings, up to 2–3× daily, for gentle digestive comfort and antioxidant support.
• Tincture (1:5, 40–60% alcohol) — Steep 2–4 weeks, strain. Use 1–2 mL in water, up to 2–3× daily. Alcohol extracts more resinous flavones for a stronger effect.
• Topical Wash or Compress — Use cooled tea or a few drops tincture diluted in water to quiet visible redness or irritation (patch-test first).
• Resin Poultice (folk) — Fresh crushed leaves applied as a cleansing poultice; modern version = warm water paste (patch-test advised).

Note: Woolly Blue Curls is potent and resinous; small amounts suffice. Avoid prolonged high-dose use; not for pregnancy. Seek professional guidance for internal use.

Modern Research & Chemistry Notes

Recent studies on Trichostema lanatum show that its resin-rich leaves contain not only aromatic oils but also unique plant polyphenols. These include special forms of apigenin, luteolin, and scutellarein—flavones with antioxidant and skin-calming potential. Laboratory extracts demonstrate selective antibacterial effects against Gram-positive bacteria (such as Staphylococcus aureus) and can lower TNF-α, a key inflammation signal. Together, these findings support traditional uses for soothing the body and point to modern applications for skin resilience and wellness. ^†

GC–MS analysis confirms the essential oil is strongly monoterpene-rich, dominated by α-thujene, with secondary contributions from pinene isomers, sabinene, β-phellandrene, and myrcene. This explains the oil’s sharp green-pine sparkle, soft herbal-floral heart, and lingering woody-balsamic veil. ^†

Perfume Note Breakdown

Top Notes (0–15 min)

• α-Thujene (~57%) → sharp peppery-green sparkle; dominant mint-pine brightness
• α/β-Pinene + Sabinene + β-Phellandrene → crisp conifer clarity, cool diffusion
• Limonene (~1%) → light citrus lift, delicate sheen

Middle (Heart) Notes (15 min–2 hrs)

• Myrcene (~7%) → herbal-balsamic depth; soft green-fruity body
• (E)-β-Ocimene (~3%) → airy floral-green nuance

Base Notes (Drydown, 2–6 hrs)

• Trace sesquiterpenes (β-caryophyllene, α-bisabolol) → soft woody-balsamic warmth, grounding persistence

Olfactory narrative: A vivid, α-thujene opening bursts with green-citrus-pine sparkle, settles into a sweet floral-herbal heart, and fades to a gentle woody-balsamic veil.

Ecological Role & Potency

Native to Southern California chaparral, Woolly Blue Curls thrives in rocky, sun-exposed soils. Its dense, velvet-like trichomes not only guard against drought but also secrete resins packed with fragrant oils and protective flavones—an adaptation that gives the plant resilience and aromatic strength. ^†
