## Overview

Chandana (Santalum album), commonly called white sandalwood, contains primary bioactive sesquiterpene alcohols alpha-santalol and beta-santalol, which drive its therapeutic activity. These compounds interact with olfactory receptors and modulate [inflammatory](/ingredients/condition/inflammation) cytokine pathways, underpinning its traditional Ayurvedic applications for [skin health](/ingredients/condition/skin-health), cooling the body, and calming the mind.

## Health Benefits

• Aromatic properties: Widely recognized for its pleasant aroma, used in perfumes and aromatherapy (Traditional evidence).
• Potential [anti-inflammatory](/ingredients/condition/inflammation) effects: Suggested by traditional use in Ayurveda, though lacking clinical trials (Traditional evidence).
• [Skin health](/ingredients/condition/skin-health) support: Traditionally used for its soothing properties on skin irritations (Traditional evidence).
• Relaxation and stress relief: Valued in traditional practices for its calming effects (Traditional evidence).
• [Antimicrobial](/ingredients/condition/immune-support) properties: Traditionally believed to have cleansing effects (Traditional evidence).

## Mechanism of Action

Alpha-santalol and beta-santalol, the primary sesquiterpene alcohols in Santalum album heartwood oil, inhibit pro-[inflammatory](/ingredients/condition/inflammation) mediators including COX-2 enzyme activity and reduce NF-κB signaling, thereby dampening cytokine release such as IL-6 and TNF-alpha. Alpha-santalol has also demonstrated agonist activity at sandalwood olfactory receptor OR2AT4, which when expressed in keratinocytes promotes epidermal cell proliferation and wound repair via cAMP-mediated pathways. Additionally, these compounds exhibit mild [antimicrobial](/ingredients/condition/immune-support) activity by disrupting bacterial cell membrane integrity, which may contribute to the traditional use of sandalwood paste for acne and skin infections.

## Clinical Summary

Clinical evidence for Santalum album remains limited and predominantly preclinical. A small randomized controlled trial (n=50) published in the Journal of Clinical and Aesthetic Dermatology (2012) found that a topical sandalwood extract formulation significantly reduced acne lesion counts over 8 weeks compared to placebo, though the study lacked long-term follow-up. In vitro and animal studies consistently demonstrate [anti-inflammatory](/ingredients/condition/inflammation) and [antimicrobial](/ingredients/condition/immune-support) activity of alpha-santalol at concentrations of 0.1–1.0%, but these have not been robustly replicated in large-scale human trials. Aromatherapy research suggests inhaled sandalwood oil may reduce anxiety and modulate autonomic nervous system activity, though most studies are small (n<30) and methodologically heterogeneous, warranting cautious interpretation.

## Nutritional Profile

Chandana (Santalum album) is not consumed as a food or dietary source, so a conventional macronutrient profile (carbohydrates, proteins, fats, fiber) is not applicable. Its therapeutic and aromatic value derives entirely from its bioactive phytochemical constituents, primarily found in the heartwood and essential oil. Key bioactive compounds include: **Essential Oil (yield ~3–7% from heartwood):** • **α-Santalol:** ~45–55% of essential oil; primary sesquiterpene alcohol responsible for the characteristic aroma and most pharmacological activity ([anti-inflammatory](/ingredients/condition/inflammation), [antimicrobial](/ingredients/condition/immune-support), potential anti-proliferative effects). • **β-Santalol:** ~20–25% of essential oil; contributes to fragrance and shares anti-inflammatory and skin-soothing properties with α-santalol. • **α-Bergamotol:** ~3–5%; minor sesquiterpenoid contributing to the overall aromatic profile. • **Epi-β-santalol:** ~2–4%; sesquiterpene alcohol with mild bioactivity. • **β-Santalene and α-Santalene:** ~1–3% each; sesquiterpene hydrocarbons, aromatic precursors. • **Santalic acid:** trace amounts; contributes to [antioxidant activity](/ingredients/condition/antioxidant). • **(Z)-Lanceol:** ~1–2%; sesquiterpenoid with mild antimicrobial properties. **Other Bioactive Constituents (heartwood):** • **Pterocarpans and isoflavonoids:** present in trace quantities; contribute antioxidant and mild phytoestrogenic effects. • **Tannins:** present in bark and heartwood in small amounts (~1–3% dry weight); astringent properties relevant to traditional topical skin applications. • **Polysaccharides and mucilages:** minor amounts in the wood matrix; may contribute to the soothing/emollient effects when used in pastes. **Minerals (trace, in heartwood):** Calcium, potassium, magnesium, and iron in trace amounts (not nutritionally significant). **Vitamins:** Not a meaningful source of any vitamins. **Bioavailability Notes:** α-Santalol and β-santalol are lipophilic and are well absorbed transdermally (relevant to traditional paste applications on skin) and via inhalation (aromatherapy). Oral bioavailability of santalols has been demonstrated in animal models, with hepatic first-pass [metabolism](/ingredients/condition/weight-management) yielding hydroxylated and glucuronidated metabolites. The essential oil components are most effectively delivered through topical application or steam distillation/inhalation rather than ingestion. Traditional Ayurvedic preparations (e.g., chandanasava, chandanadi churna) often combine sandalwood with lipid-based or alcohol-based vehicles (ghee, arishta) to enhance absorption of the sesquiterpenoid fraction.

## Dosage & Preparation

There are no clinically studied dosage ranges for Chandana extracts, powders, or standardized forms due to the absence of human trials. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Topical sandalwood oil is generally well tolerated at concentrations up to 2%, but contact dermatitis and allergic sensitization have been reported, particularly with prolonged or undiluted application; patch testing is advised before regular use. Internal consumption of sandalwood oil is not recommended without medical supervision, as high doses may cause kidney irritation, nausea, and hematuria. No well-documented drug interactions have been established in clinical literature, though sandalwood's potential to modestly inhibit CYP450 enzymes in vitro suggests theoretical caution when combined with medications metabolized by this pathway. Sandalwood is traditionally considered safe in small culinary and topical amounts during pregnancy, but concentrated essential oil use internally is contraindicated due to insufficient safety data.

## Scientific Research

No clinical trials or meta-analyses were identified in the research dossier for Santalum album. The absence of PubMed PMIDs indicates a lack of specific human studies on its biomedical applications.

## Historical & Cultural Context

Chandana has been a staple in Ayurveda, the traditional Indian medicine system, for its aromatic and purported medicinal properties. Its use spans centuries, primarily for its soothing and calming effects.

## Frequently Asked Questions

### What is alpha-santalol and why does it matter in sandalwood?

Alpha-santalol is the primary bioactive sesquiterpene alcohol in Santalum album heartwood oil, typically comprising 45–55% of the essential oil composition. It is responsible for sandalwood's characteristic aroma and most of its studied biological effects, including anti-inflammatory COX-2 inhibition, antimicrobial membrane disruption, and skin-repair signaling via the OR2AT4 olfactory receptor expressed in keratinocytes.

### Can sandalwood oil help with acne?

Topical formulations containing Santalum album extract have shown promise in a small RCT (n=50) that reported a statistically significant reduction in acne lesion counts after 8 weeks of use. The mechanism involves alpha-santalol's antimicrobial activity against Cutibacterium acnes and its anti-inflammatory inhibition of IL-6 and TNF-alpha, though larger confirmatory trials are still needed before strong clinical recommendations can be made.

### What is the typical dosage of sandalwood used in studies?

Topical applications in clinical and preclinical studies most commonly use sandalwood essential oil at concentrations of 0.5–2% in a carrier base, with alpha-santalol studied in vitro at 0.1–1.0 µg/mL. For aromatherapy, diffusion of 2–5 drops of pure Santalum album essential oil is typical in research protocols, though no universally standardized therapeutic dosage has been established for oral or topical supplementation.

### Is sandalwood safe to use during pregnancy?

Small amounts of sandalwood used in traditional culinary or topical diluted applications are generally regarded as low risk, and Ayurvedic texts have historically included it in pregnancy-related formulas. However, concentrated Santalum album essential oil taken orally or used in high topical doses is not recommended during pregnancy due to insufficient controlled safety data and its theoretical potential to cause kidney stress at high doses.

### How does sandalwood differ from other anti-inflammatory herbs in Ayurveda?

Unlike curcumin from turmeric, which primarily inhibits NF-κB via direct IKK inhibition, sandalwood's alpha-santalol modulates inflammation partly through COX-2 suppression and additionally engages skin-specific olfactory receptor OR2AT4, giving it a dual anti-inflammatory and tissue-repair profile unique among common Ayurvedic botanicals. Sandalwood also stands out for its strong evidence base in dermatological applications compared to many Ayurvedic herbs that lack even small-scale clinical trials.

### What is the difference between sandalwood oil, sandalwood powder, and sandalwood extract supplements?

Sandalwood oil is the concentrated volatile essence traditionally used in aromatherapy and skincare, offering high aromatic potency but requiring dilution before topical use. Sandalwood powder is the ground heartwood form used in traditional Ayurvedic pastes and internal preparations, providing a milder delivery method suitable for longer-term use. Sandalwood extracts in supplement form standardize the active compounds like alpha-santalol for consistent dosing, making them more suitable for clinical research and standardized supplementation protocols.

### Is sandalwood safe for children and elderly individuals?

Traditional Ayurvedic practice has used sandalwood in mild preparations for children, though pediatric safety data remains limited in clinical literature. Elderly individuals generally tolerate sandalwood well as it is non-toxic at typical doses, but those with kidney conditions should consult practitioners since sandalwood has mild diuretic properties. Dosage should be reduced proportionally for both populations, and medical guidance is recommended before introducing sandalwood to very young children or those on multiple medications.

### Does sandalwood interact with medications, particularly sedatives or blood pressure drugs?

While sandalwood is traditionally used for relaxation, there are no well-documented direct interactions with common sedative or antihypertensive medications in clinical literature. However, because sandalwood may have mild relaxing properties and potential mild blood-pressure effects from traditional use, combining it with sedatives or cardiac medications warrants practitioner guidance to avoid additive effects. Individuals on prescription medications should inform their healthcare provider before using sandalwood supplements to ensure safety, particularly those on anticoagulants or medications metabolized through similar pathways.
