Rohitakarishta in classical Ayurveda

What it is

Rohitakarishta is a fermented liquid Ayurvedic formulation (an arishta). Its chief ingredient is the stem bark of Rohitaka: Tecomella undulata (Sm.) Seem., a deciduous tree of the Bignoniaceae family native to the arid regions of northwestern India, also called desert teak or Marwar teak (review of the species).

The Ayurvedic Formulary of India, Part II, gives the official composition: Rohitaka stem bark is decocted in water and the decoction reduced. Jaggery (guda) and Dhataki flowers (Woodfordia fruticosa) are added, along with twelve prakshepa dravyas: Pippali, Pippalimula, Cavya, Citraka, Shunthi, Tvak, Ela, Patra (Tejapatra), Haritaki, Bibhitaka, and Amalaki. The mixture is fermented for about a month, generating 5–10% self-produced alcohol (formulary composition reproduced here, and here). Its classical reference is the Bhaishajya Ratnavali, in the chapter on spleen disorders (classical reference noted here).

Classical properties

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

Traditional use

In classical Ayurvedic practice, Rohitakarishta is a fermented preparation of liver (yakrit) and spleen (pleeha) care, described for their enlargement, as well as loss of appetite (agnimandhya), jaundice (kamala), abdominal disorders, constipation, and sprue. These are traditional indications recorded in formulary and classical texts, not clinically proven effects (peer-reviewed review of traditional uses; formulary indications). A modern integrative review notes that Rohitaka is described in Ayurveda for yakrit vikara (liver disorders), pandu (anaemia), krimi (worm infestation), kushta (skin disease), and shotha (inflammation), and that Rohitakarishta and Rohitakadi churna have incorporated the plant for centuries for hepatic and splenic enlargement (review).

What research has looked at

No human clinical trials of Rohitakarishta itself were found. All modern evidence below concerns extracts of its key ingredient, Rohitaka bark: which is not the same as the fermented formulation.

Liver protection

In a 2012 Journal of Ethnopharmacology study, a methanolic stem-bark extract of Tecomella undulata, and its isolated constituent betulinic acid, protected human HepG2 liver cells in vitro and prevented carbon-tetrachloride–induced liver injury in rats, as judged by blood markers of liver damage, antioxidant levels, lipid peroxidation, and liver histology (in-vitro + animal study) (study abstract). A 2023 rat study found that bark extract given for 15 days significantly lowered AST, ALT, and ALP after acetaminophen-induced liver damage; the study used the drug N-acetylcysteine as a comparison (animal study) (study). This is not evidence of a treatment for liver injury. Never use it in place of, or alongside, prescribed medicine without your doctor. A separate rat study reported that stem-bark extract protected against isoniazid-induced liver injury, assessed by liver enzymes and liver histopathology (animal study) (study). These are promising preclinical results, but they do not prove the arishta works in people.

Blood sugar

An integrative review reports that aqueous and methanolic extracts of the whole plant lowered fasting blood glucose and improved glucose tolerance in streptozotocin-induced diabetic rats (animal study) (review). This is preliminary animal evidence only.

Antioxidant and anti-inflammatory activity

The same review reports that ethanolic bark extract raised antioxidant defences (SOD, catalase, glutathione) and reduced pro-inflammatory cytokines (TNF-α, IL-1β) in animal models (animal study) (review). Human relevance is unknown.

Antimicrobial activity

Ethanolic bark extracts have shown antibacterial activity against various gram-positive and gram-negative bacterial strains in laboratory cultures (in-vitro study) (review). This does not translate to infection treatment in humans.

Safety notes

No published human safety studies of Rohitakarishta were found. Because it is a fermented arishta, it contains 5–10% self-generated alcohol (per the formulary), so it is unsuitable for children, during pregnancy and breastfeeding, and for anyone avoiding alcohol. People with gastritis or a sensitive stomach should use it only under medical supervision: formulary references note that higher doses may cause a burning sensation in the stomach. Safety data is limited: talk to a clinician before use, especially if you take liver-related or diabetes medication.

FAQs

What is Rohitakarishta used for?

Traditionally, Rohitakarishta is used in Ayurveda for enlargement of the liver and spleen, jaundice, loss of appetite, abdominal disorders, constipation, and sprue. These are classical and formulary indications recorded in texts like the Bhaishajya Ratnavali: they reflect traditional practice, not clinically proven effects. Modern research has only tested Rohitaka bark extracts in animals and cell cultures, so anyone considering it for a liver condition should first consult a qualified practitioner and get proper medical evaluation.

Is there scientific evidence that it protects the liver?

There is preclinical evidence for the key ingredient, not the finished arishta. A 2012 Journal of Ethnopharmacology study showed Tecomella undulata bark extract and its betulinic acid protected rat livers from chemical injury, and later rat studies confirmed protection against acetaminophen- and isoniazid-induced damage. However, no human trials of Rohitakarishta exist, so a liver-protective effect in people is unproven and it should never replace medical treatment for liver disease.

How is Rohitakarishta different from Rohitaka churna?

Rohitaka churna is simply the powdered bark of Tecomella undulata, while Rohitakarishta is a fermented liquid in which a decoction of the bark is fermented with jaggery, Dhataki flowers, and twelve additional herbs and spices (including triphala, pippali, ginger, and cinnamon) for about a month. The fermentation generates 5–10% alcohol. Both share the same chief ingredient and traditional liver–spleen indications, but they are different dosage forms with different preparation methods.

Can people with diabetes take Rohitakarishta?

Caution is warranted. The formulary recipe uses a large quantity of jaggery, so the finished arishta contains residual sugars alongside its 5–10% alcohol content. Animal studies suggest Rohitaka extracts may lower blood sugar, which could theoretically interact with diabetes medication: but this is untested in humans. People with diabetes should not use it without a clinician's guidance and should monitor blood glucose if a practitioner prescribes it.

Is Rohitakarishta safe in pregnancy?

There are no safety studies of Rohitakarishta in pregnancy, and as a fermented preparation it contains 5–10% self-generated alcohol. For that reason alone it should be avoided during pregnancy and breastfeeding. Anyone who is pregnant, planning pregnancy, or nursing should not use it and should discuss any liver or digestive concern with their doctor and a qualified Ayurvedic practitioner instead.

Does Rohitakarishta have side effects?

No formal safety studies exist, so the side-effect profile is not well characterised. Formulary references warn that higher doses may cause gastric burning, and people with gastritis or sensitive stomachs are advised to use it only under supervision. Because of its alcohol content, it may interact with sedatives and is unsuitable for children and people with alcohol dependence. Report any adverse effect to your practitioner.
