Wild Rosemary Extract
Also known as: Rosemary, Wild Rosemary, Rosmarinus officinalis
Overview
*Rosmarinus officinalis*, commonly known as Rosemary or Wild Rosemary, is a perennial herb native to the Mediterranean region. It is acclaimed for its aromatic leaves and flowers, widely utilized in culinary applications as well as traditional herbal medicine. Due to its high levels of antioxidants, flavonoids, and phenolic compounds, rosemary is recognized for a variety of health benefits including its roles as a carminative, antispasmodic, painkiller, and circulatory tonic. Research on rosemary primarily includes extensive in vitro studies and animal trials, with moderate evidence supporting its efficacy. However, human studies are limited and often lack rigorous methodology. The extract is available in several forms including capsules, teas, and essential oils, making it quite versatile for both culinary and therapeutic uses.
Benefits
Rosemary exhibits several evidence-based benefits. Its antioxidant activity is well-documented, showing significant results in assays like DPPH and ABTS, suggesting its potential as an effective free radical scavenger. In vitro studies also indicate anti-hyperglycemic effects, with rosemary extracts inhibiting enzymes critical to glucose metabolism, potentially benefiting individuals with diabetes. Furthermore, there are indications of immunomodulatory properties, although substantial human evidence remains scarce. Cognitive enhancement has been a traditional use, with anecdotal support; however, robust clinical studies are lacking to fully validate this claim. The strength of these benefits is corroborated by various high-quality in vitro studies, although there remain gaps in human data which necessitate further exploration.
How it works
The primary mechanism of action for rosemary is believed to be its antioxidant properties, primarily through the activity of compounds such as carnosol, which engages antioxidant pathways and may inhibit glucose metabolism enzymes. This interaction potentially modulates the immune response and supports cognitive functions through related biological pathways. However, detailed elucidation of these mechanisms in humans is still needed as current data predominantly stems from animal and in vitro research, with bioavailability in humans not extensively studied.
Side effects
Rosemary is generally considered safe when consumed as part of a typical diet; however, adverse effects may occur. Common side effects (>5%) include gastrointestinal upset and potential allergic reactions in sensitive individuals. Uncommon side effects (1-5%) lack precise documentation, while rare side effects (<1%) may involve severe allergic reactions or interactions with certain medications. Particularly noteworthy is rosemary's potential to interact with anticoagulant drugs or diabetes medications, which may necessitate caution. Pregnant or breastfeeding women should avoid rosemary extract due to insufficient safety data. Special caution is advised for those with bleeding disorders or on anticoagulant therapy, highlighting the importance of consulting healthcare providers before starting any supplementation.
Dosage
Specific dosing guidelines for rosemary extract are not well-established. Commonly reported dosages vary widely, typically aligning with culinary amounts in food. While there is no defined minimum effective dose for specific health outcomes, the optimal dosage generally depends on the form of supplementation used: capsules, teas, and essential oils. It is advised to adhere to recommended dosages on product labels and consider starting at lower amounts to assess tolerance. High doses may lead to gastrointestinal distress, and while maximum safe levels are not clearly defined, caution is integral when consuming concentrated forms. Timing considerations are not clinically documented, thus taking rosemary as per individual routines is suggested, while absorption may be influenced by the extraction method employed.
FAQs
