Rohitaka

What is Rohitaka?

Rohitaka is the bark of a small hardy tree, Tecomella undulata, that stands in the dry, sandy country of north-western India. It is a tree built for hard ground: it holds its own through long drought, throws out bright flowers in the bare season, and grows where softer plants would fail. In the desert districts it is one of the few trees to give real timber, and the wood is prized enough that the tree carries the English names desert teak and Marwar teak.

The Sanskrit name points to colour. Rohita carries the sense of red, and the name is read as marking the reddish tinge the tradition associates with the tree, in its wood and its flowers. In the country where it grows it is known plainly as Rohida. It is the bark that Ayurveda uses, taken from the trunk and prepared for medicine.

What Ayurveda uses it for

Rohitaka is, before all else, the bark of the pliha, the spleen. When the classical writers describe a herb that acts on the spleen, this is the one they name first, and its foremost use in the texts is for the enlargement and disorders of that organ. Close beside this stands its action on the yakrit, the seat the tradition links with bile and blood. Around these two the rest of its uses gather.

The bark is described as bhedana, a herb that breaks up and clears what has gathered and hardened, and as krimighna, acting against worms. It is bitter and astringent, light and dry, and by these qualities the texts hold it to settle the Kapha and Pitta doshas together. That combination, breaking and clearing while cooling the heat the tradition connects with bile, is what places the bark so firmly in the abdominal disorders.

Within that role the dravyaguna texts describe the bark as traditionally indicated in a familiar set of conditions, each named here in its classical Sanskrit term with a plain gloss:

• Pliha-roga and Pliha-vriddhi: disorders and enlargement of the spleen, the bark’s foremost and defining use.
• Yakrit-roga: disorders of the liver in the classical sense, the seat the tradition connects with bile and blood.
• Gulma: the classical category of abdominal masses, where its breaking, clearing quality is called upon.
• Pandu: the classical group marked by pallor and weakness, long linked with the spleen and blood.
• Krimi: the classical category of worms, for which the bark is named.
• Arsha: the classical category of haemorrhoids.
• Kushtha: the classical group of skin disorders.

These are the traditional textual indications recorded in the classical literature. They set out how Ayurveda has long understood the herb and are given for reference and study, not as statements of medical effect or as advice to treat any condition.

Its qualities, in plain words

Ayurveda describes every herb by a short list of qualities, and for Rohitaka they line up behind its work on the abdomen.

Its taste is bitter with an astringent edge, and in Ayurveda these are the tastes that dry and clear rather than feed. It is light and dry, so it does not add heaviness or moisture to the body but lifts and disperses, which suits a bark meant to break up what has gathered. It is cooling, and this is the quality that answers the heat the tradition connects with bile and with Pitta. It finishes pungent after digestion, a sign of a herb that stirs and clears rather than builds. Put together, these qualities describe a light, dry, cooling bark that breaks and moves, which is why the tradition settles it so firmly on the spleen and the seat of bile, and why it is held to pacify Kapha and Pitta together.

How it is taken

The usual form is the bark, given as a powder, a churna, or prepared as a decoction, a kwatha, drawn out in water. Being bitter and astringent, it was rarely taken alone as a pleasant tonic; it was reckoned a working bark for the abdomen and combined accordingly.

The best known preparation is Rohitakarishta, a classical fermented liquid, an arishta, made with the bark as its central ingredient, in which its spleen-acting quality is carried in a matured, self-generated medium. The bark also appears in decoctions and compound powders aimed at the spleen and the seat of bile, where the classical writers paired it with other herbs of like action. As with the other clearing herbs, the vehicle and the pairing were chosen to match the aim.

Good to know

Rohitaka belongs to the clearing and breaking side of Ayurveda, not the nourishing side. It is a light, dry, bitter bark, named for the spleen and the seat of bile and blood, and taken as a considered preparation rather than a daily tonic. Its long-standing reputation rests on that one clear role: the bark the classical writers reach for when the spleen is the concern.

This entry describes the classical Ayurvedic understanding of the herb. It is not medical advice, and anyone with a health condition should speak to a qualified practitioner.

Frequently asked

Which part of the tree is used? The bark. Rohitaka is a timber tree valued for its wood, but in Ayurveda it is the bark, taken from the trunk and prepared as a powder or decoction, that the classical preparations call for.

What is Rohitaka best known for? For the pliha, the spleen. It is the bark the classical writers name first for disorders and enlargement of the spleen, and beside this for the yakrit, the seat the tradition links with bile and blood.

Is Rohitaka cooling or warming? Cooling. Its bitter, astringent, light and dry nature, together with its cooling quality, is why the tradition holds it to settle the Kapha and Pitta doshas and reaches for it in the heat the classical texts connect with bile.
