What is Water Willow?
Willows have a long reputation as fever bark, and the Ayurvedic tradition has its own waterside version. Water Willow, known in Sanskrit as Jalvetasa (जलवेतस), "the willow of the water", is a large tree that grows near water bodies, up to about 5000 feet.
Botanically it is listed as Salix tetrasperma Roxb., with the English names Indian Willow and Water Willow; it is also associated with Salix caprea, the goat willow. The bark is the medicinal part.
The Bhavaprakash Nighantu treats it as interchangeable with other willow (Vetasa) species. Its uses are the willow's classic trio: reducing fever, binding through astringency, and helping in bleeding disorders.
Benefits of Water Willow
Water Willow is bitter and astringent (Tikta, Kashaya Rasa), light and dry (Laghu, Ruksha Guna), with a cold potency (Sheeta Virya) and a pungent post-digestive effect (Katu Vipaka). The Bhavaprakash Nighantu records that it balances Pitta, the dosha of heat and metabolism.
Bleeding Disorders
Its first listed action is alleviating bleeding disorders (Raktapittahara). Our knowledge graph links it to bleeding disorders (Raktapitta), a classical term for bleeding driven by excess heat in the blood.
Fever
Water Willow is an antipyretic (Jvaraghna). Its bitter taste and cooling potency are the qualities behind this role.
Astringent Binding
It is also classed as astringent (Stambhana), meaning it checks and holds back excess flow. This supports its use where something is leaking, such as bleeding.
Properties and uses are similar to Vetasa: antipyretic, astringent, and useful in bleeding disorders.

How to Use Water Willow
The bark is the part of Water Willow used in medicine. Our sources do not record a dose or a specific preparation, so treat the table below as orientation and have a practitioner set the amount.
| Form | Dose | Best For | When to Take |
|---|---|---|---|
| Bark | Practitioner guided | Fever, bleeding disorders | As advised |
| Other willow (Vetasa) bark | Practitioner guided | Used interchangeably, per the classical text | As advised |
Bleeding of any kind needs a proper diagnosis first. Water Willow belongs in a plan made with a doctor or practitioner, not in place of one.
Safety & Side Effects
Our sources do not list formal contraindications for Water Willow, but its nature and its chemistry suggest clear cautions.
- Salicin content: our records list salicin among its constituents. If you take blood thinners, aspirin or similar medicines, or have an aspirin allergy, talk to your doctor before using willow bark.
- Bleeding is a symptom: unexplained bleeding needs medical assessment. Do not self-treat it.
- Dry and astringent: it is light and dry (Laghu, Ruksha) and binding, so it may aggravate constipation or dryness.
- Pregnancy, nursing and children: no safety data is recorded. Avoid unless a practitioner prescribes it.
Recommended: Start Here
If Water Willow interests you, the sensible first step is to discuss willow bark with a qualified practitioner, especially for bleeding concerns, which always need diagnosis. If you are cleared to use it, willow bark is the form you are most likely to find.
Look for products that name the willow species on the label, since the classical text treats several willows as interchangeable but buyers should still know what they have.

Safety note: willow bark contains salicin, so avoid it if you take blood thinners or are allergic to aspirin, and avoid it in pregnancy unless prescribed.
