Bhurja (Betula utilis): Benefits, Evidence & Safety

TL;DR

Bhurja is Himalayan birch bark, used in Ayurveda for skin and wounds. The modern evidence is all preclinical: a 2023 rat study of a bark-extract hydrogel showed antibacterial effects and wound contraction, and the bark contains betulin-type triterpenes. No human trials support any medicinal use.

What it is

Bhurja is the Sanskrit name for the bark of Betula utilis D. Don (family Betulaceae), the Himalayan birch, also known as bhojpatra and famous as an ancient writing material. It is a high-altitude tree of the Himalayas, and the stem bark is the part used medicinally. Phytochemical work reports that the bark contains triterpenoids (betulinic acid and oleanolic acid prominent), along with phenolic compounds and flavonoids. One profiling study analyzed 27 bark accessions from four Indian regions and quantified ten analytes, with betulinic and oleanolic acids the most abundant (phytochemical study).

Traditional use

An Ayurvedic literature review describes bhurja bark in classical practice for skin disorders, ear pain, wounds and related external applications (Ayurvedic review, IJAPR). These are records of traditional use, not clinical proof. The human evidence is assessed separately below, and it is thin.

What modern research says

Wound healing (preclinical only)

A 2023 laboratory study prepared a sodium-alginate hydrogel from B. utilis bark extract and tested it for antibacterial activity and wound healing in a rat wound model: the optimized formulation produced 19 mm and 9 mm zones of inhibition and 93% wound contraction in rats (preclinical study). Real numbers, and I take them seriously as far as they go. They go exactly this far: this is animal and formulation-specific evidence. It does not show that applying raw bark, or taking bark orally, heals wounds in humans.

Triterpene chemistry

The bark's signature compounds are the triterpenes betulinic acid and oleanolic acid, which a 27-accession profiling study found to be the most abundant of its ten quantified analytes (phytochemical study). The bark's antibacterial and wound-healing activity in laboratory models comes from the 2023 hydrogel study described below. A separate review of betulin notes clinical research on standardized birch-bark extracts, but those products are derived from European birch species, not B. utilis, and their results cannot be transferred to Himalayan birch bark preparations (betulin review).

What the evidence does not support (yet)

No human clinical trial of bhurja bark, oral or topical, was identified in the reviewed sources. There is no clinical evidence that it treats skin disease, ear pain, infections or wounds in people, and no evidence for any internal medicinal use.

Safety & contraindications

Safety data for bhurja bark, especially oral use, are limited. The available modern studies are preclinical and tested extracts or gels, not traditional oral preparations. In the absence of human safety data, pregnant and breastfeeding women should avoid medicinal use, and anyone considering it should consult a qualified clinician first. People with a known birch allergy should be cautious with birch-derived topical products as a general precaution, and should stop use if skin irritation occurs.

FAQs

What is bhurja?

Bhurja is the bark of Betula utilis, the Himalayan birch (also called bhojpatra). It is a high-altitude Himalayan tree whose bark contains betulinic acid, oleanolic acid, phenolics and flavonoids. Ayurvedic literature describes its traditional use for skin disorders, ear pain and wounds, but these are traditional records rather than clinically proven effects. (Sources; Ayurvedic review)

Does bhurja heal wounds?

Only in animals so far. A 2023 study found that a hydrogel made from B. utilis bark extract showed antibacterial activity and promoted wound healing in a rat wound model (19 mm and 9 mm inhibition zones, 93% wound contraction). No human trials have tested bhurja bark, as a gel, poultice or oral preparation, for wound healing, so this remains preclinical evidence, not proof of benefit in people. (Source)

Can I take bhurja bark powder internally?

There is no clinical evidence supporting internal use of bhurja bark, and no verified pharmacopoeial or trial-based dose exists. The modern studies tested bark extracts in the laboratory or as a topical hydrogel in animals, not oral bark powder in humans. Without human efficacy or safety data, oral use cannot be recommended; consult a qualified Ayurvedic practitioner rather than self-dosing.

Is bhurja the same as the birch bark used in European medicines?

No. Standardized birch-bark extract products researched in Europe are made from European birch species, not the Himalayan Betula utilis. Although both contain betulin-type compounds, the species, preparation methods and tested products differ, so clinical findings from European birch-bark extracts do not transfer to bhurja bark. (Source)

Is bhurja safe in pregnancy?

Safety in pregnancy and breastfeeding is unknown. No adequate human studies were found. Because medicinal bhurja preparations have essentially no human safety data, pregnant and breastfeeding women should avoid them and discuss any medicinal use with a clinician first.

Where does bhurja grow, and is it sustainable?

Betula utilis grows at high altitudes across the Himalayas. No species-specific sustainability assessment for B. utilis bark harvesting was located in the reviewed sources, so the sustainability of wild collection is unknown from this review. Buyers who care about sustainability should ask suppliers for documented cultivated or sustainably harvested sources.
