Rosemary (Rosmarinus officinalis)
What rosemary is, how it is traditionally used, what published studies show and where they fall short, how to use it safely, and which GraceYes products contain it.
What it is
A Mediterranean herb, used here as leaf powder and as essential oil. It is not a classical Indian ingredient. The EU herbal monograph recognises 6–10% rosemary oil on skin as a traditional remedy for minor muscle and circulation complaints (EMA).
Key compounds
1,8-cineole, camphor, carnosic acid, rosmarinic acid.
What studies show
- Rosemary oil and 2% minoxidil both increased hair count at 6 months in androgenetic alopecia, with no difference between them. Scalp itch was lower with rosemary. The trial had 100 people and no placebo group (PubMed).
- Rosemary leaf extract improved hair regrowth in mice and inhibited 5α-reductase (PubMed).
- An oil blend of thyme, rosemary, lavender and cedarwood improved alopecia areata in 44% of people versus 15% with carrier oil alone (n=86). The result belongs to the blend, not to rosemary alone (PubMed).
Safety
Dilute it. Do not use on broken skin. Safety is not established under 18 or in pregnancy.
