Sandalwood

Also known as: Sandalwood, Santal, Chandan, Santalum album

Overview

Sandalwood, specifically derived from the heartwood of the *Santalum album* tree, is famous for its aromatic essential oil. It has a long history of use in various applications, including aromatherapy, traditional medicine, perfumes, and incense. The oil, rich in sesquiterpene alcohols like santalol, is thought to offer various therapeutic benefits such as stress reduction, improved sleep, and skin health. While traditional uses are well-documented, the scientific evidence supporting these effects is developing, and more rigorous studies are necessary to validate many claims. Sandalwood oil is often used in personal care products due to its antimicrobial and anti-inflammatory properties. However, the evidence remains limited and varies in quality, with many studies featuring small sample sizes and differing methodologies.

Benefits

Sandalwood oil is suggested to provide multiple benefits supported by varying levels of evidence. Notably, it may aid in stress reduction and enhance sleep quality, backed by a systematic review indicating positive psychological health outcomes from aromatherapy using essential oils. Topically, sandalwood exhibits antimicrobial and anti-inflammatory actions accountable for its skin health benefits. Furthermore, it may offer analgesic properties and help alleviate nausea, although the evidence for these claims is weak and largely derived from general aromatherapy studies rather than specific investigations into sandalwood oil. Overall, while a general population may benefit from its properties, targeted studies identifying specific demographic advantages are minimal.

How it works

The therapeutic effects of sandalwood oil are likely mediated by its active compounds, primarily sesquiterpene alcohols like santalol. These compounds may engage with various biological pathways, facilitating anti-inflammatory and antimicrobial effects. Sandalwood oil can interact with the nervous system, promoting calmness and relaxation, particularly when inhaled. Furthermore, it displays antimicrobial and anti-inflammatory actions when applied topically, though specific molecular targets and pathways remain under-researched.

Side effects

Sandalwood oil is generally considered safe for use when applied in moderation, yet it can cause skin irritation in sensitive individuals, which is noted as a common side effect. Rarely, allergic reactions may occur, but no serious side effects have been well documented. Due to limited data, potential interactions with other medications remain uncertain, necessitating caution when combining sandalwood oil with other treatments, especially during pregnancy and breastfeeding, where safety data is lacking. Special populations, including children and those with sensitive skin, should exercise caution when using sandalwood oil. Always conduct a patch test prior to extensive topical use to mitigate risks of skin irritation.

Dosage

The optimal dosage of sandalwood oil varies significantly due to the lack of standardized dosing guidelines backed by strong evidence. For aromatherapy, a few drops are typically sufficient when diffused or inhaled directly from a cloth. In topical applications, users should dilute sandalwood oil with a carrier oil to avoid skin irritation. There is no defined maximum safe dose, but excessive application may lead to adverse skin reactions. Timing for usage is generally based on personal preference or necessity, with no specific recommendations available. Factors such as concentration and formulation also influence absorption rates.
