Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Borage seed oil has one of the highest known GLA contents of any plant oil (typically 20-26%), the basis of its anti-inflammatory reputation.
Unsaturated pyrrolizidine alkaloids present in the whole herb are hepatotoxic and genotoxic on cumulative exposure, limiting internal whole-herb use; the refined seed oil is largely free of them.
Contribute to the plant's traditional demulcent and astringent properties.
A nucleoside analogue considered the marker bioactive compound, studied for anti-inflammatory, antioxidant and metabolic effects.
Immunomodulatory and antioxidant polysaccharides, a major focus of both oral and topical product development.
Additional characteristic fungal sterol and nucleoside constituents.

Safety, Cautions & Contraindications
Pyrrolizidine alkaloids (PAs): Many Boraginaceae can produce PAs; unsaturated PAs are hepatotoxic and genotoxic (risk increases with cumulative exposure). Borage as food/tea: PA presence in borage consumed as herb/tea has been specifically studied; EU has set PA maximum levels for certain foods including borage (context for why sourcing/limits matter). Pregnancy/breastfeeding: avoid internal use of borage herb products due to PA-related concerns and risk uncertainty. Liver disease / long-term use: avoid (PA risk + cumulative exposure logic). Seed oil vs herb: refined/quality-controlled seed oil is generally the preferred form when borage is used medicinally, because the main target compound is GLA; however, product quality and contamination control still matter. Drug interactions (caution): GLA oils have been discussed with anticoagulants (bleeding risk caution is better established for evening primrose oil; borage oil is often grouped in the same “GLA oil” category). Use caution if on anticoagulants/antiplatelets.
Duke (2002) rates borage as a single-plus herb (+) with predominantly folklore-level evidence. Borage seed oil is rich in gamma-linolenic acid (GLA) and has been used for inflammatory conditions such as arthritis and PMS, and for cardiovascular support; typical dose is one 300 mg softgel containing 24% GLA or 2-4 ml liquid leaf extract. Commission E does not approve borage for any indication, and the herb contains hepatotoxic and carcinogenic pyrrolizidine alkaloids, making long-term use inadvisable (Duke, 2002).
Generally well tolerated short-term in human studies, but research is still limited (Ontawong et al., 2024; Hirsch et al., 2016). Possible side effects: stomach upset, nausea, diarrhea, headache (reported broadly for “Cordyceps” supplements; not everyone gets this) (Jędrejko, Lazur and Muszyńska, 2021). Avoid / use medical guidance if you have: autoimmune disease, you’re on immunosuppressants, you have a bleeding disorder, or you take blood thinners/antiplatelet drugs (theoretical interaction + caution used in reviews) (Jędrejko, Lazur and Muszyńska, 2021). Pregnancy/lactation: not enough safety data → best to avoid (Jędrejko, Lazur and Muszyńska, 2021). Quality matters: choose reputable brands with testing for contaminants and clear labeling (fruiting body vs mycelium; extract ratio) (Jędrejko et al., 2022).

Botanical Description
Robust, bristly annual herb with hollow, branching stems covered in coarse, stiff hairs. The leaves are large, oval and wrinkled, also coarsely hairy, and smell of cucumber when crushed. The flowers are strikingly bright blue, star-shaped with five pointed petals and a prominent black central cone of anthers, borne in nodding clusters.[1]
Entomopathogenic fungus (not a true plant) that develops from a mycelium infecting and consuming an insect host - classically a moth caterpillar or pupa buried in the soil. In late season it produces a slender, bright orange, club-shaped fruiting body (stroma) that emerges from the ground above the mummified host, its surface minutely roughened with embedded spore-producing structures.[4]
Habitat
Grows readily on disturbed, nutrient-rich ground, gardens, waste places and field margins; native to the Mediterranean region and widely naturalised and cultivated across Europe and elsewhere as a culinary and oil-seed crop.[1]
Grows on insect larvae and pupae in cool, moist forest soils and grassland across temperate and alpine East Asia; commercially, most Cordyceps militaris is now cultivated on grain or insect-based substrate rather than wild-collected.[4]
Harvesting
Leaves and flowers are picked fresh through the growing season, at their best just as the flowers open; the seed is collected in late summer once the seed heads have dried, pressed for its gamma-linolenic-acid-rich oil.[1]
Wild fruiting bodies are dug up carefully with the insect host attached, in autumn when they emerge; cultivated material is harvested from the growing substrate once the orange fruiting bodies mature, then dried.
Traditional Uses
Borage has a long folk reputation, reflected in the old saying 'borage for courage', as a mood-lifting, cooling herb for feverish colds and respiratory complaints, and as a digestive and anti-inflammatory remedy; the fresh leaves and flowers have also been used culinarily. Modern use is centred on the seed oil, rich in gamma-linolenic acid (GLA), for inflammatory and skin conditions.[1]
Preparations
Cultivated fruiting-body extract, standardised to cordycepin or polysaccharide content, taken as capsules or powder.
Dosage
A phase-two randomised placebo-controlled trial in moderate persistent asthma used Borago officinalis extract at 5 mL three times daily for one month. Because of pyrrolizidine alkaloid content, whole-herb (leaf/flower) preparations should only be used short-term and from PA-controlled sources; avoid in pregnancy, breastfeeding and liver disease. Educational reference only, not a prescription.
