Patola

TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Parwal

What the texts say Patola does

• Deepana — kindles digestion (appetiser)
• Pachana — digests ama (digestive)
• Kushthaghna — used in skin disease
• Jwaraghna — used in fever
• Krimighna — anthelmintic (against worms)
• Hridya — good for the heart

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

Side effects and limits

The fruit is an ordinary vegetable eaten in quantity across eastern India. The leaf is a bitter medicinal article and is a different thing. No significant toxicity is recorded for either. Anyone pregnant, on medication or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Avoid or ask first: No absolute contraindication is documented here. This is written deliberately rather than left blank.

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

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Of the leaf, which is the medicinal article.

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.

Tikta with ushna virya and katu vipaka. A bitter that warms, and one of the few bitters the texts call tridoshahara.

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.

Tiktottama, the best of the bitters, names the leaf and not the vegetable, which is the distinction a student needs.

The commonest error is not adulteration but the wrong part: the cultivated fruit sold as parwal is a vegetable and is not the bitter leaf the texts prescribe. Trichosanthes cucumerina is also supplied as Patola in the south with regional authority behind it.

Trichosanthes dioica is the accepted Patola. Trichosanthes cucumerina, the snake gourd, is used as Patola in parts of south India, and the classical descriptions of the bitter-leaved Patola fit it better than the cultivated vegetable does.

A WAY TO REMEMBER IT

Trichosanthes is Greek thrix, hair, and anthos, flower — the fringed petals. Dioica means the male and female flowers are on separate plants, which is why a patch that never fruits is not diseased but simply male.

Patola heads the Patoladi gana of the Sushruta Samhita and is one of the dravya of Panchatikta. That is what the tradition records and where.

• 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.
