Names and identification

Language	Name
English	Pattanga
Latin/Botanical	Caesalpinia sappan L.

Key Phytochemical Constituents

• Brazilin (neoflavonoid - primary bioactive compound)
• Brazilein (oxidized form of brazilin)
• Sappanone A and B (homoisoflavonoids)
• 4-O-Methylsappanol
• Protosappanin A, B, C
• Caesalpin (diterpene)
• 3-Deoxysappanchalcone (chalcone)
• Sappanchalcone

How does it work?

• Brazilin melanin synthesis suppression: Brazilin inhibits forskolin-stimulated cAMP-mediated MITF expression, downregulating tyrosinase and TRP-1/TRP-2 transcription, directly reducing melanin production in melanocytes for skin brightening
• Brazilin anti-inflammatory NO and PGE2 inhibition: Brazilin and protosappanins suppress iNOS and COX-2 expression, reducing nitric oxide and prostaglandin E2 production in activated macrophages, alleviating skin inflammation
• Sappanone homoisoflavonoid antioxidant protection: Sappanone A and B scavenge superoxide and hydroxyl radicals
• Collagen synthesis and wound closure promotion: Brazilin-rich extract stimulates fibroblast migration and proliferation, enhances collagen deposition, and accelerates wound epithelialization

Which traditional uses are supported by research?

These summaries come from the source notes, which do not name the studies behind them.

• Complexion enhancement (Varnya): traditionally used for complexion enhancement. An in vitro study in human melanoma cells reported that brazilin suppressed melanin synthesis.
• Wound healing (Vrana Ropana): traditionally used for wound healing. An animal study reported improved incision wound healing with sappanwood extract.
• Anti-inflammatory skin care (Daha Prashamana): traditionally used in skin care for inflammatory conditions. Studies have reported inhibition of NO and PGE2 production through iNOS and COX-2 suppression.

What do recent studies show?

• Sucita RE, Fikri F, Purnomo A and others 2024. The efficacy of topically applied Sappan wood (Caesalpinia sappan L.) ethanol extract during incision wound healing in albino rats. Open veterinary journal. PMID 39175965 · doi:10.5455/OVJ.2024.v14.i7.5
  A 6.5% sappanwood ethanol extract demonstrated significant improvement in incision wound healing in albino rats, with enhanced tissue repair attributed to brazilin and related bioactive secondary metabolites.
• Mitani K, Takano F, Kawabata T and others 2013. Suppression of melanin synthesis by the phenolic constituents of sappanwood (Caesalpinia sappan). Planta medica. PMID 23154842 · doi:10.1055/s-0032-1327897
  Brazilin and 4-O-methylsappanol strongly suppressed melanin synthesis in human melanoma HMV-II cells stimulated with forskolin, suggesting a possible mechanism relevant to the traditional complexion-enhancing use.

Recent safety updates

• Generally regarded as safe in traditional medicine at recommended doses. Heartwood has been used as a natural food coloring and traditional medicine for centuries. No significant toxicity reported in animal studies at therapeutic doses
• Red pigment (brazilin/brazilein) may stain skin and fabrics. Limited formal clinical safety data in humans; most evidence from animal models. Species is sometimes confused with Caesalpinia echinata (pernambuco wood) - proper botanical identification essential
