Sandalwood Oil
Also known as: Sandalwood Oil, Santalum album Oil
Overview
Sandalwood oil is an essential oil derived from the heartwood of *Santalum album*, a tree native to India and Southeast Asia. It is characterized by its distinctive fragrance and is widely used in perfumery, aromatherapy, and as a flavoring agent. The oil's primary constituent, alpha-santalol, is believed to contribute to its therapeutic properties. Sandalwood oil is traditionally used for its calming effects, as a skin care ingredient, and in traditional medicine for various ailments. While it has a long history of use, the scientific evidence supporting its benefits is limited, with most studies being small-scale or observational. More rigorous clinical trials are needed to fully establish its efficacy and safety.
Benefits
Sandalwood oil is often used for its potential calming and relaxing effects, although specific quantified outcomes are not well-established. Some in vitro and animal studies suggest it may possess antioxidant, antiviral, and bactericidal properties. However, there is limited evidence on specific population benefits, such as for anxiety or sleep disorders. Due to the lack of large-scale clinical trials, effect sizes and clinical significance are not well-defined. The time course of any potential benefits is also not well-documented. Overall, the evidence supporting the benefits of sandalwood oil is preliminary and requires further investigation.
How it works
Sandalwood oil's mechanism of action is not fully understood. It is believed to interact with the nervous system to produce calming effects, but the specific biological pathways involved are not well-defined. The oil may influence mood and stress responses, although detailed mechanisms remain unclear. Alpha-santalol, a major component of sandalwood oil, is known to have biological activity, but its specific molecular targets are not well-defined. The absorption and bioavailability of sandalwood oil components have not been extensively studied, limiting our understanding of how it interacts with the body.
Side effects
Sandalwood oil is generally considered safe at current use levels, with low acute oral and dermal toxicity. The most common side effect is occasional skin irritation or sensitization reactions. Uncommon and rare side effects are not well-documented. No significant drug interactions have been reported. While there are no specific contraindications, caution is advised for individuals with sensitive skin. Limited data are available on the use of sandalwood oil in pregnant or breastfeeding women, so caution is advised in these populations. Individuals should perform a patch test before widespread topical application to assess for potential skin sensitivity.
Dosage
Specific dosage recommendations for sandalwood oil are not well-established due to limited clinical research. It is typically used in aromatherapy or diluted for topical applications, with specific dosages varying depending on the intended use. A minimum effective dose and maximum safe dose have not been determined. For aromatherapy, use in well-ventilated areas is recommended. For topical use, dilution is necessary to avoid skin irritation. Absorption factors have not been well-studied. Due to the lack of comprehensive data, it is important to use sandalwood oil cautiously and follow product-specific guidelines.
