Rasna

TRADITIONAL VIEW, WITH SAFETY LIMITS

What the texts say Rasna does

• Vatahara — pacifies vata
• Shothahara — reduces swelling
• Amapachana — digests ama
• Vedanasthapana — relieves pain
• Kasahara — relieves cough

What the evidence says. Traditional use is extensive and long recorded. Modern clinical evidence is limited.

Side effects and limits

• Digestive upset
• Allergic reaction in those sensitive to Asteraceae

Avoid or ask first: Known allergy to plants of the Asteraceae family, where Pluchea is the source.; Pregnancy.

A traditional classification, not a recommendation. The full safety record is below.

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Rasna is a name with no settled plant. Which species is in the product changes the drug.

Reported from Sharangadhara Samhita and the Ayurvedic Pharmacopoeia of India. Laisha states what the texts prescribe; it does not recommend. No quantity here is adjusted for a particular person — not for agni, koshtha, bala, age, pregnancy, kidney or liver function, or anything already being taken.

Ayurvedic Pharmacopoeia of India, Part I

Pluchea lanceolata in the north, Alpinia galanga in the south, and Vanda roxburghii in some practice. Three different plants under one name.

These are the marker and the identity test for this dravya, and they are not a test Laisha has run on anything. Laisha does not state the numeric limits here: the assay, ash and extractive figures must be read from the current edition of the Ayurvedic Pharmacopoeia of India, because a wrong limit printed here is a number a laboratory would act on. The entries in this library that DO carry figures carry them because each one was checked.

Tikta with ushna virya and katu vipaka.

These are the actions the classical texts record. They are statements about what the tradition holds, and this library does not restate them as findings about a human body.

Elaparni, cardamom-leaved, points to Alpinia galanga rather than to Pluchea, which is itself evidence that the classical Rasna may not have been the plant most commonly sold as Rasna today.

Rasa, guna, virya, vipaka and karma are recorded as the classical texts give them, with the text and section named so a student can open the book and check. Where an exact chapter and verse could not be confirmed, this library names the section rather than inventing a number.

This is a name, not a plant, and a student should say so. Pluchea lanceolata is used across north India and is what the Ayurvedic Pharmacopoeia of India takes as the source. Alpinia galanga is used in the south and in Kerala, and the paryaya Elaparni fits it better than it fits Pluchea. Vanda roxburghii, an orchid, is used in Bengal. Inula racemosa is used in some places. Four plants, three families, one name — and a Rasnadi Kwatha made in Kerala is not the same medicine as one made in Uttar Pradesh.

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Rasna is a name with no settled plant behind it — at least four species are used across India, and the Ayurvedic Pharmacopoeia and regional practice do not agree. That is set out below rather than smoothed over.

A WAY TO REMEMBER IT

Pluchea honours the Abbé Pluche. Lanceolata means lance-shaped leaf. Remember it as the name with no settled plant: Rasna is a name, and Pluchea is only the Pharmacopoeia's answer to it.

Rasna is described in the Bhavaprakasha Nighantu and is named throughout the classical literature for joint disorders. That is what the tradition holds and where it is written down, not a finding about what the plant does in a body.

Constituents. Pluchea lanceolata carries flavonoids and sterols including quercetin derivatives. Alpinia galanga, used under the same name, carries an entirely different chemistry dominated by phenylpropanoids.

• This is a study and clinical reference for practitioners and students. The matra and anupana it records are what the classical texts and the Ayurvedic Pharmacopoeia of India PRESCRIBE — Laisha reports them, it does not recommend them. They are not a prescription for any particular person, and they are not adjusted for your age, agni, koshtha, bala, pregnancy, kidney or liver function, or anything else you are already taking. Only a qualified practitioner who has examined you can do that.
• Traditional classification is recorded as what the classical texts say, with the text and the place in it named so it can be checked. It is not restated as a finding about a human body.
• Nothing here replaces a qualified Ayurvedic practitioner or a doctor.
