Red Sandalwood

Red Sandalwood seed contains naphthoquinones like Santalin A and B that inhibit inflammatory cytokines TNF-α and IL-6 while providing 83.4% DPPH radical scavenging activity at 25 mg/mL. The flavonoids quercetin and kaempferol glycosides enhance antioxidant enzyme activity including SOD, CAT, and GPx to support cellular protection.

Origin & History

Red Sandalwood (*Pterocarpus santalinus*) is a precious tree native to South Asia, particularly India and Sri Lanka, thriving in dry deciduous forests. Revered in traditional medicine, its wood and extracts are valued for potent anti-inflammatory, detoxifying, and skin-rejuvenating properties.

Historical & Cultural Context

Red Sandalwood has been traditionally revered for millennia in Ayurvedic, Unani, and Chinese medicine for promoting skin health, liver detoxification, and blood circulation. It was also used in rituals and medicinal formulations symbolizing purity, beauty, and vitality. Modern research now validates its antioxidant, anti-inflammatory, cardiovascular, and neuroprotective benefits.

Health Benefits

- Supports liver detoxification by enhancing enzymatic activity and cellular regeneration.
- Promotes skin vitality by reducing oxidative stress and stimulating collagen synthesis.
- Enhances cardiovascular health by improving circulation and reducing arterial stiffness.
- Regulates metabolism by stabilizing blood sugar and optimizing lipid profiles.
- Provides neuroprotective benefits through inflammation reduction and cognitive support.
- Fortifies immune function and aids wound healing through its bioactive compounds.
- Supports digestive enhancement and reduces gastrointestinal inflammation.

How It Works

Savinin inhibits TNF-α production in LPS-stimulated RAW264.7 cells at 25 µg/mL through modulation of inflammatory pathways. Phenolic compounds including caffeic and gallic acids provide antimicrobial effects while inhibiting α-glucosidase and α-amylase enzymes for metabolic regulation. The naphthoquinones Santalin A and B demonstrate concentration-dependent antioxidant activity by scavenging DPPH radicals and enhancing endogenous antioxidant enzymes.

Scientific Research

Research, including in vitro and animal studies, highlights Red Sandalwood's liver-cleansing, metabolic-regulating, cardiovascular, and skin-supportive actions. Studies also indicate its immune-enhancing and anti-inflammatory effects, validating many traditional uses. Further human clinical trials are needed to fully elucidate its therapeutic potential.

Clinical Summary

Current evidence is limited to preclinical in vitro and animal studies with no published human clinical trials. Animal studies demonstrate hepatoprotective effects against CCl4 toxicity and enhanced kidney antioxidant enzyme activity in rats. In vitro research shows moderate antidiabetic potential with isolated compounds inhibiting digestive enzymes, though less potent than acarbose reference (IC50 7.46-27.46 µg/mL). The anti-inflammatory effects of savinin and antioxidant activity of methanolic extracts require validation through human clinical trials.

Safety & Interactions

Safety data from human studies is lacking, with evidence limited to preclinical research showing no reported toxicity at tested concentrations up to 200 µg/mL. Phenolic compounds may inhibit thyroid peroxidase, warranting caution in individuals with thyroid disorders or those taking thyroid medications. High tannin content could potentially cause gastrointestinal irritation with excessive consumption. Traditional use suggests avoiding during pregnancy and lactation, and potential interactions with antidiabetic medications due to α-glucosidase inhibition should be considered.
