Rohitaka in Ayurveda: Properties & Everyday Use

What it is

Rohitaka is the Ayurvedic drug obtained from Tecomella undulata (Sm.) Seem., a small deciduous tree in the family Bignoniaceae native to the arid regions of northwestern India, Pakistan, and Arabia, where it is also known as rohida, roheda, or desert teak (integrative review, 2025; overview). The stem bark is the part traded and studied as the drug (pharmacognosy study). The genuine botanical source is recognized in the Ayurvedic Pharmacopoeia of India, though substitute barks circulate in the raw-drug trade because the tree is scarce (classical appraisal, 2020). The species is regarded as endangered, and the recent review literature calls for conservation alongside research (integrative review, 2025). Reported phytoconstituents include quinonoids (including deoxylapachol), iridoid glucosides (including tecoside), and flavonoids (including quercetin and rutin), along with ursolic acid (integrative review, 2025; overview).

Classical properties

• Taste (rasa): bitter (Tikta), astringent (Kashaya)
• Qualities (guna): light (Laghu), dry (Ruksha)
• Potency (virya): cooling (Sheeta)
• After digestion (vipaka): pungent (Katu)
• Doshas: traditionally said to settle Pitta and Kapha; may increase Vata

Traditional use

In Ayurveda, rohitaka is best known in classical liver and spleen care, indicated for hepatomegaly (enlarged liver) and splenic disorders: the classical texts describe it in conditions called yakrut-pleeha disorders, including jaundice-related (kamala) syndromes (classical appraisal, 2020). Folk and classical records also describe its use for various skin ailments and as a "blood purifier" (integrative review, 2025). These are traditional indications, not clinical proof; the modern research is assessed separately below.

What research has looked at

Liver protection (animal studies)

Preclinical studies of T. undulata bark extracts report hepatoprotective activity in rodent models of liver injury, and recent work has extended this to models relevant to nonalcoholic steatohepatitis (NASH): findings the review literature describes as robust within the animal-study domain (integrative review, 2025). No human trials have tested rohitaka for liver disease.

Inflammation, pain, and infection (animal and laboratory studies)

The same review catalogues anti-inflammatory, analgesic, and antimicrobial activities from in-vitro and animal experiments, attributed collectively to the plant's quinonoid, iridoid-glucoside, and flavonoid constituents (integrative review, 2025). All of this evidence is preclinical.

What the evidence does not support (yet)

The 2025 integrative review is explicit: the lack of rigorous, well-designed human clinical trials is the most significant hurdle for rohitaka, and most published work relies on crude or semi-purified extracts rather than standardized preparations (integrative review, 2025). Traditional claims for liver, spleen, and skin disorders therefore remain unvalidated in humans.

Safety notes

No human safety data for rohitaka were identified. The review literature considers crude extracts relatively safe in animal studies, while noting that specific isolated phytochemicals or nonpolar fractions may carry inherent toxicity (integrative review, 2025). There are no data on pregnancy, breastfeeding, or drug interactions. Because the genuine bark is scarce and substitutes circulate in trade, product identity is an additional practical concern.

FAQs

What is rohitaka?

Rohitaka is the Ayurvedic drug obtained from Tecomella undulata (the stem bark being the traded part), a desert tree of northwestern India (also called rohida or desert teak) recognized in the Ayurvedic Pharmacopoeia of India (classical appraisal, 2020).

Why is rohitaka called a liver herb?

Ayurvedic texts describe it as a liver and spleen tonic used for hepatomegaly and jaundice-related disorders: its signature traditional indication (classical appraisal, 2020). This is a traditional claim, not a clinically proven effect.

Does rohitaka work for liver problems?

Unknown in humans. Animal studies report liver-protective effects, including in NASH-relevant models, but no human clinical trials exist (integrative review, 2025). It should not be used as a treatment for liver disease without medical supervision.

Is rohitaka endangered?

The species is regarded as endangered, and recent reviews call for conservation strategies alongside research to ensure sustainable use (integrative review, 2025).

Is rohitaka safe?

Human safety data are lacking. Animal studies suggest crude extracts are relatively safe at tested doses, but isolated compounds may be toxic, and there are no data for pregnancy, breastfeeding, or drug interactions (integrative review, 2025).

What is the recommended dose of rohitaka?

Swastik does not suggest amounts. The right amount depends on the person, the preparation and the product, so check with a qualified Ayurvedic practitioner or your doctor before taking any herb.
