Rosmarinus Prostratus

Rosemary contains rosmarinic acid and carnosic acid, which act as antioxidants protecting neural cells from oxidative damage. These compounds may inhibit acetylcholinesterase, the enzyme that breaks down acetylcholine, potentially supporting cognitive function. For circulation, rosemary's camphor content may stimulate blood flow through mild vasodilation. Evidence level C indicates these mechanisms are supported by preliminary research and traditional use, though more clinical trials are needed to confirm effects in humans.

Rosemary may interact with anticoagulant and antiplatelet medications such as warfarin, aspirin, and clopidogrel due to its mild anticoagulant properties, potentially increasing bleeding risk. Rosemary may also interact with diabetes medications by affecting blood glucose levels, and with lithium by altering its elimination from the body. Always consult a healthcare provider before using rosemary medicinally if you take prescription medications, as interactions can affect drug efficacy.

The standard adult dosage for rosemary tea is 2-4 grams of dried herb steeped in hot water, consumed up to three times daily. For essential oil use, apply 3-5 drops diluted in a carrier oil or water topically. Do not ingest rosemary essential oil internally without professional guidance. Dosage recommendations are based on traditional use and pharmacopoeial standards (Evidence level C). Start with lower doses to assess individual tolerance.

Rosemary is considered unsafe during pregnancy when used in medicinal doses. High doses can stimulate uterine contractions and potentially cause miscarriage. While small culinary amounts in food are generally acceptable, concentrated extracts, teas, and essential oils should be avoided throughout pregnancy. Breastfeeding women should also exercise caution, as insufficient safety data exists for rosemary use during lactation. Consult a qualified healthcare provider for personalized guidance.

Rosemary has been traditionally used as a hair growth stimulant and circulatory tonic for the scalp. Its active compounds, including rosmarinic acid and ursolic acid, may improve circulation to hair follicles and possess anti-inflammatory properties. Preliminary research suggests rosemary oil may support hair growth, though evidence remains limited (Evidence level C). Apply diluted rosemary essential oil (3-5 drops per tablespoon of carrier oil) to the scalp and massage gently for potential benefits.

Rosemary is generally well-tolerated in culinary amounts. Medicinal doses may cause rare side effects including skin sensitization or allergic reactions, particularly with topical essential oil application. Individuals with epilepsy should avoid rosemary entirely, as the camphor content may potentially trigger seizures in susceptible individuals. Other possible effects include stomach upset or allergic contact dermatitis. Discontinue use if adverse reactions occur and consult a healthcare provider.
