रोहेड़ा — Rajasthan का State Tree (Marwar Teak)। 48°C, 100mm rainfall, pure sand में survive! Rohitaka: 3,000-yr liver/jaundice Ayurveda। Timber: Rs.1,500-3,000/cubic ft। Mehrangarh Fort woodwork। Bishnoi sacred।
Rohida (Tecomella undulata) — Roheda / Marwar Teak / Desert Teak / Rohitaka — is Rajasthan's State Tree and one of India's most drought-resistant and ecologically important trees of the Thar Desert and semi-arid regions. Called "Marwar Teak" because its wood quality rivals teak in hardness and durability, Rohida is remarkable for thriving in conditions where even hardy desert trees struggle — it tolerates temperatures up to 48°C, survives on rainfall as low as 100-150mm per year, and grows in pure sand dunes and rocky desert soils. The tree produces extraordinary orange-yellow trumpet-shaped flowers (February-April) that transform the bleak Rajasthan desert into spectacular color — the timing before leaves appear makes the display even more dramatic. In Ayurveda, Rohida is known as Rohitaka — one of the most important liver medicines. The bark of Rohida has been used for 3,000+ years for liver diseases, jaundice, and spleen disorders. Modern research has confirmed significant hepatoprotective (liver-protecting) activity. The wood is also one of Rajasthan's most prized commercial timbers — hard, durable, termite-resistant, beautifully grained — used in the finest Rajasthani furniture, doors, and carved woodwork that are internationally renowned.

Rohida bark liver — Ayurvedic: Rohitaka: Charaka, Sushruta, Ashtanga Hridayam में kamala (jaundice), pliha (spleen), yakrit roga (liver) के लिए primary treatment। Rohitukine — unique flavone alkaloid। Confirmed hepatoprotective। Rohitukine: anti-cancer research (CDK inhibition — blood cancers)। Preparation: (1) Bark decoction: 10g + 500ml → 200ml। 100ml twice daily 3-4 weeks। (2) Powder: 3-5g + honey। (3) + Bhumiamalaki: classical jaundice combination। (4) Rohidarak Rishta: classical formulation। Caution: severe acute hepatitis — hepatologist first। Infants: NEVER self-medicate। Alcohol-related: stop alcohol completely, then adjunct। Pharmaceutical research: rohitukine as anti-cancer drug lead — CDK2/CDK9।
Rohida State Tree — significance: 1983 में declared। Ecological: extreme conditions adapt — 48°C, 100-500mm, sandy/rocky। Other commercial timber trees इन conditions में survive नहीं। Desert में premium timber — unique। Historical: Mehrangarh Fort, Junagarh Fort, Umaid Bhawan Palace — Rohida wood। Rajasthani carved doors, jharokas — Rohida। Cultural: Bishnoi community की sacred ecology — centuries से protect। 1730 Khejarli Massacre — 363 Bishnois trees (including Rohida) protect करते हुए lives दिए। History का greatest environmental conservation act। Commercial: Rs.1,500-3,000/cubic foot → illegal felling target। Conservation threatened despite State Tree protection।
Rohida desert survival: Water access: deep taproot (6-10 metres) — deep groundwater। Sand dunes पर visible moisture नहीं — taproot far below water found। Water conservation: small waxy leaves — transpiration reduce। Deciduous — hottest months (May-June) में leaves shed। Flowers before leaves — reproduction before maximum heat। Bark: grey-brown — heat reflect। Slightly corky — inner tissues insulate। Fire tolerance। Growth strategy: slow growth = dense timber = termite resistance। Deep root anchoring: desert storms (aandhi) में survive। Temperature tolerance: 48°C protein denaturation prevent। Comparison: fruit trees >40°C die। Neem: 44-45°C। Rohida: 48°C। Climate change adaptation: temperature बढ़ने पर Rohida की importance बढ़ेगी।
