Hastikarna Palasha in Ayurveda: Properties & Everyday Use

What it is

Hastikarna palasha (Leea macrophylla Roxb., Vitaceae) is a large shrub of eastern India, named for leaves that can reach the size of an elephant's ear (hastikarna). Despite the name, it is not a true palasha (Butea monosperma); the shared name reflects resemblance in traditional grouping, not botany. Roots and leaves are the parts used in folk medicine.

Classical properties

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

Traditional use

Traditional and folk sources describe it for the joints, skin and injuries: painful swellings, joint complaints, wounds, and skin afflictions, with the root used internally and leaves applied externally. These are traditional descriptions, not clinical proof; the research record is examined separately below.

What research has looked at

Anti-inflammatory effects in cells and rodents

A study published in Food and Chemical Toxicology found that extracts of Leea macrophylla modulated inflammatory mediators in cell-based assays, supporting an anti-inflammatory mechanism at the cellular level (Food Chem. Toxicol., 2013). A separate rodent study reported that the plant's extracts reduced experimentally induced inflammation, pain, and fever in animals (PMC7892933).

These are consistent, mechanistically plausible signals — the kind of early evidence that justifies further study. They are not evidence that the plant relieves arthritis, injury pain, or fever in humans.

What the evidence does not support (yet)

Every human use. No clinical trial has tested hastikarna palasha in people for pain, inflammation, wounds, or anything else. Traditional dosing, preparation methods, and safety margins are all unvalidated.

Safety notes

No human safety data for Leea macrophylla were identified. Animal studies showing pharmacological activity do not establish safety; they establish that the plant is biologically active, which cuts both ways. Avoid in pregnancy and breastfeeding (no data). And don't use it as a substitute for proven pain or anti-inflammatory treatment without professional guidance.

FAQs

What is hastikarna palasha?

Leea macrophylla, a large-leaved shrub of eastern India used in folk medicine for inflammation, pain, and wounds. It is not the same plant as palasha (Butea monosperma).

Does research support it for pain or inflammation?

In animals and cells, yes: extracts reduced inflammatory mediators, pain, and fever in rodent and cell models. No human trials exist (Food Chem. Toxicol., 2013; PMC7892933).

Is it safe?

Unknown in humans. No safety trials were identified. Biologically active in animals is not the same as safe in people.

Can I use the leaves on wounds?

Traditional external use exists, but without safety or efficacy data, infected or serious wounds belong to a clinician, not a folk poultice.

What is the recommended dose of hastikarna palasha?

Swastik does not suggest amounts. The right amount depends on the person, the preparation and the product, so check with a qualified Ayurvedic practitioner or your doctor before taking any herb.

Sources

Cell-level anti-inflammatory findings: the 2013 Food and Chemical Toxicology study of Leea macrophylla extracts on inflammatory mediators (abstract). Rodent findings: the study reporting anti-inflammatory, analgesic, and antipyretic effects in animals (PMC7892933). No human clinical trials of Leea macrophylla were identified.
