Gol-e gāv-zabān is the Persian mood-and-heart tea, pink-tinted and lightly sweetened with nabāt. Most of what is sold in Iran is Echium amoenum rather than true European borage.
Take it in cycles of two to three weeks rather than continuously. Its alkaloids (strong plant compounds that act on the body even in small amounts) load the liver.
Anyone drinking it daily should stick to certified PA-free flowers.
The Persian borage flower — gol-e gāv-zabān — has been brewed for centuries as a gentle heart and mood tonic. Its violet-blue petals tinge the tea pink and carry a long folkloric reputation for chasing away sorrow.
Known to botanists as Borago officinalis / Echium amoenum.
Persian gol-e gāv-zabān (Echium amoenum) is an upright biennial 30–60 cm tall with rough hairy lance-shaped leaves and striking deep violet-blue funnel-shaped flowers borne in branching clusters in spring. The dried flowers are the principal medicinal portion. European borage (Borago officinalis) is similar but bears five-petalled star-shaped blue flowers.
Family: Boraginaceae (borage family).
It also acts as a mild diaphoretic, supporting the body through a cold, and the flowers carry polyphenols (protective plant compounds).
Persian temperament: Warm & Moist (1st degree — flower). Ibn Sīnā (Canon, Book II) and Aghili Khorasani (Makhzan al-Adwiya) class gol-e gāv-zabān as warm and moist in the 1st degree — a mufarrih al-qalb (heart-gladdener) that lifts melancholy (sawdā'), calms a restless heart, and softens a cold-dry constitution. The classical Persian household damkardeh for grief, exam stress, and sleepless nights.
Persian medicine reads borage (گل گاوزبان) as warm and moist and places it among the heart-gladdeners, prescribed less for a physical complaint than for a mood: the flat, heavy melancholy of a cold-dry constitution, anxiety that keeps someone awake, the low weeks after grief or illness.
Because it's moistening, it suits dry, tense people especially, and the classical cup pairs the violet flowers with a little rose or lemon to keep the infusion (a drink made by steeping the plant in hot water) from feeling cloying. Modern practice adds one caution the old texts lacked: brief courses only, given the liver-loading alkaloids.
It was used: melancholy, grief, and anxious heart (mufarriḥ al-qalb). Restless sleep paired with low spirits; mild colds and chills: gentle diaphoretic; heart palpitations of nervous origin. Recovery from emotional shock or exhaustion.
Borage is traditionally uplifting for mood and calming before sleep. That is the role the Persian household actually keeps it for.
Steeped with sugar candy (nabāt), gol-e gāv-zabān tea is the Persian grandmother's remedy for grief, exam stress, and sleepless nights.
Damnoosh-e gol-e gāv-zabān: classical Persian damkardeh — 1 tsp dried petals + nabāt in a covered cup of just-boiled water, 10 min.
Persian melancholy blend: gol-e gāv-zabān + a pinch of saffron + 1 tsp rosewater for grief, anxiety, and a heavy heart.
Sharbat-e gāv-zabān is concentrated borage-flower syrup, 1 Tbsp in cool water, used in summer for restless hearts.
Primary compounds
Rosmarinic acid is the dominant Boraginaceae polyphenol (protective plant compounds). Anti-inflammatory antioxidant with modest anxiolytic (calms anxiety) direction in animal models.
Anthocyanins (delphinidin, cyanidin glycosides) — responsible for the deep violet-blue petal colour and the pink hue in tea. Polyphenol (protective plant compounds) antioxidant load.
Cyanogenic-free saponins (soap-like plant compounds) are traditional soft demulcent (coats and soothes irritated tissue) action.
Trace pyrrolizidine alkaloids (variable by cultivar and source) — the reason PA-free certified flowers matter.
Gamma-linolenic acid (GLA) is present in the seed oil (not the flower tea). Anti-inflammatory omega-6.
Other notable constituents
Notable: Volatile oils (the concentrated aromatic oil of the plant)
Strong evidence
Pyrrolizidine-alkaloid content varies by species, cultivar, and part of the plant. Regulatory bodies advise PA-free certified products and time-limited use.Strong evidence
Moderate evidence
Borage seed oil (GLA-rich) may modestly improve inflammatory-arthritis symptoms — not the same preparation as the flower tea.Moderate evidence
Early research
Echium amoenum (Persian borage) flower extract may reduce mild-to-moderate anxiety and depressive symptoms over 4–6 weeks vs placebo in small human trials.Emerging evidence
E. Amoenum aqueous extract reduced obsessive–compulsive symptoms as adjunctive therapy in a small 6-week randomised trial.Emerging evidence
Damkardeh: 1 tsp dried flowers per cup, covered 8 min, with nabāt or honey · Sleep blend: gol-e gāv-zabān + chamomile + linden + a pinch of rose.
Borage syrup: flowers simmered with sugar and rosewater, 1 Tbsp at bedtime.
Bath: strong infusion added to warm water for nervous tension.
Steep 1 tsp dried petals in hot water 5–10 min.
Combine with rosewater before bed.
Anticoagulants (warfarin, DOACs) — GLA in borage seed oil may modestly reduce platelet aggregation — flower tea negligible, but concentrated seed-oil supplements warrant physician oversight. (moderate concern)
Hepatotoxic drugs & alcohol — Non-certified PA-containing preparations add to hepatic load — always use certified PA-free products; avoid daily continuous use beyond 4–6 weeks. (moderate concern)
Antiseizure medications (phenobarbital, phenytoin, carbamazepine) — Theoretical lowering of seizure threshold reported with high borage seed oil doses — avoid concentrated extracts alongside epilepsy therapy. (low concern)
Avoid medicinal doses in pregnancy or with liver conditions.
Active liver disease (avoid non-certified PA-containing preparations).
Borage seed oil contains GLA — use only PA-free certified products.
Pregnancy and breastfeeding (medicinal doses).
Anticoagulant therapy (use cautiously — mild blood-thinning potential).
Pregnancy and breastfeeding
Avoid medicinal doses (concentrated flower tea daily, sharbat, seed oil capsules) in pregnancy — limited safety data and pyrrolizidine-alkaloid concern. Occasional culinary or ceremonial cup isn't the issue; regular daily therapeutic use is.
Children
Half-strength cup of PA-free flower infusion, lightly sweetened, is a traditional Persian calming tea from around age 4; skip honey under age 1. Concentrated seed oil not routinely used in children.
Older adults
One of the gentlest Persian household mood teas for the sixth and seventh decade — grief, sleeplessness with worry, a heavy heart. Use in cycles of 2–3 weeks; review anticoagulant (blood-thinning medicines) and hepatic-medication interactions before daily use.
What about pyrrolizidine alkaloids (PAs)?
Some Boraginaceae plants contain PAs, which can stress the liver in large or prolonged doses. Choose certified PA-free borage products, keep daily use modest (1–2 cups for a few weeks), and avoid in pregnancy and liver conditions.
What does borage tea taste like?
Soft, slightly sweet, and faintly cucumber-like, with a pink hue once nabāt is added. The aroma is gentler than chamomile and beloved by people who find chamomile too bitter.
