AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Classical keshya and raktapradara use.

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.

Kashaya and madhura with sheeta 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.

Rakta pushpi and Arunapushpa both name the red flower, and the tradition is specific that the red single form is meant — a distinction a student should carry into a garden centre.

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.

Double-flowered and coloured garden varieties are sold and used where the texts mean the red single form. Hibiscus sabdariffa, roselle, is a different species used for a sour drink and is sometimes called hibiscus without qualification; it has its own quite different profile including a documented effect on blood pressure.

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. The red single-flowered form is the one the texts mean; the many double and coloured garden forms are not the medicinal article.

A WAY TO REMEMBER IT

Hibiscus is an old Greek name for mallow. Rosa-sinensis means rose of China. Japa means the flower offered while chanting.

Japa is described in the Bhavaprakasha Nighantu among the flowers and is recorded as keshya. That is what the tradition holds and where it is written down, not a finding about what the flower does in a body.

Constituents. The flower carries anthocyanins, flavonoids and a large amount of mucilage, which is what gives hair preparations their slip.

• 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.
