Birch: Benefits, Uses & Dosage

Some of the oldest surviving Sanskrit manuscripts were written not on paper but on bark. That bark came from the Himalayan birch, whose thin, papery layers peel away in sheets. Ayurveda knows the same tree as a medicine for the skin and for worms.

Birch, in Sanskrit Bhurja (भूर्ज) and in Hindi Bhojpatra, is the Himalayan Silver Birch, Betula utilis D. Don. The Bhavaprakash Nighantu describes it growing in the Himalayas at 7,000 to 12,000 feet, reaching 50 to 70 feet tall. One Sanskrit synonym, Lekhanapatra, literally means "writing leaf."

The bark is the medicinal part. It contains betulin, a triterpene, along with tannins, and its essential oil has antiseptic properties. Sushruta Samhita lists Bhurja in the Salasaradi group of drugs (Sutra Sthana 38.8).

Skin Health

The Bhavaprakash Nighantu calls Birch anti-dermatosis (Kusthaghna) and says the bark is useful in skin diseases. That links it to skin disorders (Kushtha), the classical umbrella for chronic skin complaints.

The reasoning lies in its taste. Birch is astringent (Kashaya) and bitter (Tikta), with a cooling potency (Sheeta Virya). In Ayurveda, bitter and astringent tastes are the classic pairing for clearing heat and excess moisture from the skin.

Worm Infestations

Birch is listed as anthelmintic (Krimighna), a remedy for parasites and worms (Krimi). Its light (Laghu) and dry (Ruksha) qualities suit this drying, clearing action.

Wound Care

The text also lists Birch as a wound cleanser (Vranashodhana). Its astringent tannins and the antiseptic essential oil of the bark support this traditional use.

Birch is used as bark, usually powdered. The Bhavaprakash Nighantu gives a powder (Churna) dose that is small, which reflects how strongly astringent the bark is.

The text also lists a much larger bark dose measured in tola, a heavier unit, which most likely refers to a decoction rather than a powder taken directly. Internal use should be guided by a qualified practitioner.

Our classical sources do not record specific contraindications, drug interactions or overdose signs for Birch. It is a lesser-known remedy, and the safety data is thin.

Some caution follows from its properties. Birch is light, dry and cooling, so heavy or long use could aggravate dryness. If you already have dry skin, constipation or a strong Vata tendency, keep doses small.

Worm infestations and chronic skin conditions should be diagnosed properly. Use Birch under the guidance of a qualified practitioner, especially internally.

Birch sits in a group of astringent tree barks. The most useful comparisons are with herbs grouped alongside it in the classical texts.

Pregnancy & Nursing

Our sources do not address Birch in pregnancy or nursing. Avoid internal use during these times unless a qualified practitioner specifically recommends it.

Children

No pediatric dose is recorded. Worms are common in children, but they need proper diagnosis; do not give Birch powder to a child without professional advice.

Elderly

Older people tend toward dryness, and Birch is dry and light. External use is the safer route; keep any internal dose small and supervised.

Athletes

There is no specific athletic use in our sources. As a wound cleanser, an external Birch wash may suit minor scrapes.
