Borage Herb (Borago officinalis): The Adrenal Restorative
By Anjela Jeganathan – Holistic Medical Herbalist | Herba Naturalle
Borage — Borago officinalis — is a striking annual with intense blue star-shaped flowers and coarse, bristly leaves, native to the Mediterranean and now widely naturalised across Britain. Known since ancient times as a herb of courage and cheer — the Roman naturalist Pliny wrote that “Borage brings always courage” — it was used to lift the spirits of soldiers before battle and to restore those who had been worn down by effort and anxiety. In modern herbal practice, this traditional reputation maps onto a specific physiological application: adrenal gland support and recovery from chronic stress.
At Herba Naturalle, Borage is listed in the comprehensive herb index alongside other adrenal and nervine tonics as a herb of particular relevance for the modern epidemic of adrenal depletion and stress-related fatigue.
Active Compounds
- Gamma-linolenic acid (GLA) — in the seed oil (18–26% of fatty acids); the primary source of Borage’s anti-inflammatory significance in supplement form
- Mucilage — soothing and demulcent; relevant in the aerial herb
- Pyrrolizidine alkaloids (trace) — in the aerial herb; safety consideration for long-term use
- Potassium and calcium — mineral support for adrenal and nervous system function
- Tannins and saponins — anti-inflammatory contributions
Clinical Applications
Adrenal Support
The traditional and Eclectic herbal use of Borage herb as an adrenal restorative is its most distinctive clinical application. The adrenal glands produce cortisol and adrenaline — the primary stress hormones — and in states of chronic stress and burnout, the adrenal glands can become functionally depleted, leading to fatigue, poor stress resilience, low blood pressure, and diminished immune function. Borage herb is traditionally used to support and restore adrenal function in this depleted state. The Nervous System Reset Bundle provides comprehensive adrenal and nervous system support.
Anti-inflammatory (Borage Seed Oil)
Borage seed oil is one of the richest plant sources of GLA — a precursor to anti-inflammatory prostaglandins (PGE1 series). Clinical trials have demonstrated benefits in rheumatoid arthritis, atopic eczema, and other inflammatory conditions with Borage seed oil supplementation. The Smooth Muscle and Immune Reset Bundle addresses the deeper inflammatory layer.
Respiratory and Fever Support
The fresh herb has diaphoretic and expectorant properties — used in traditional medicine for colds, fevers, and chest complaints. The Lungwort Plus supports lower respiratory health.
⚠ Safety Considerations
- Pyrrolizidine alkaloids: Present in trace amounts in the aerial herb — limit internal use to short courses; use certified pyrrolizidine-alkaloid-free preparations for long-term use
- Pregnancy: Contraindicated
- Borage seed oil: Generally safe for long-term use as the oil is essentially pyrrolizidine-alkaloid-free
- Anticoagulants: GLA may have mild antiplatelet effects
