Key Constituents

Allicin and organosulfur compounds (ajoene, S-allyl-cysteine)[1, 2, 6, 7, 8]

Allicin (diallyl thiosulfinate), formed enzymatically when raw garlic is crushed, together with ajoene and the aged-garlic compound S-allyl-cysteine, are the principal bioactives behind garlic's antimicrobial and cardiovascular effects — acting partly by raising nitric oxide and by targeting microbial thiol-containing enzymes.

Allicin / organosulfur thiosulfinatesOrganosulfur compounds
Macrocyclic ellagitannins (notably oenothein B)[4, 5, 6, 7, 8, 13]

Characteristic Epilobium polyphenols underlying the anti-inflammatory and prostate activity; a genus review identifies oenothein B as the dominant constituent and likely driver of the antimicrobial, anti-inflammatory, anti-proliferative and antioxidant effects.

Safety, Cautions & Contraindications

Safety note[9, 10, 13, 14, 15, 16]Caution

Garlic is generally very safe at culinary and supplemental doses for most healthy adults. Raw garlic contains allicin (formed when crushed) at concentrations that can irritate the gastrointestinal tract — nausea, heartburn, flatulence, and diarrhoea are the most common side effects, especially with large amounts of raw garlic on an empty stomach. Garlic may inhibit platelet aggregation and enhance anticoagulant effects of warfarin — use caution with blood-thinning medications, especially before surgery (stop 7–10 days prior). May lower blood pressure and blood sugar — caution when combined with antihypertensive or antidiabetic medications. Topical raw garlic can cause chemical burns (contact dermatitis) and should not be applied undiluted to skin for prolonged periods. Odour (from allicin metabolites) affects breath and perspiration. Pregnancy: culinary amounts safe; avoid medicinal-dose supplements due to blood-thinning risk (National Center for Complementary and Integrative Health, 2021).

Safety note[9, 10, 13, 14, 15, 16, 25]Caution

Duke (2002) rates garlic as +++ with exceptional clinical evidence (score 3) for antiseptic activity, and score 2 for anti-aggregant (antiplatelet), antiatherosclerotic, antiatherogenic, antibacterial, and antimycotic effects — among the most clinically validated herbal medicines. Commission E approves garlic for arteriosclerosis prevention and elevated blood lipids. Dose: 4 g (1 clove) fresh garlic daily, or 300 mg standardized dry powder extract (1.3% allicin) three times daily. Important interaction: garlic significantly potentiates anticoagulant medications (warfarin, aspirin) due to its anti-aggregant effects; use with caution in patients on blood thinners (Duke, 2002).

Safety note[15]Info

Lower urinary tract / prostate symptoms must be medically assessed first to exclude prostate cancer; willowherb is a supportive measure, not a substitute for diagnosis and treatment.

Safety note[15]Info

Well tolerated over three months in clinical use; longer-term safety data are limited.

Botanical Description

Bulbous perennial herb usually grown as an annual, forming an underground compound bulb ('head') of several angular cloves wrapped in papery white to purplish skin. The leaves are flat, narrow and strap-shaped, greyish-green, arising from the bulb. A tall, leafless flowering stem (scape) may rise from the bulb bearing a rounded umbel of small pink-white flowers, often mixed with small bulbils, though cultivated garlic rarely sets true seed.[1]

Height: 30-100 cm (flowering scape)
Habit: Bulbous perennial herb, usually grown as an annual
Leaves: Flat, narrow, strap-shaped, greyish-green
Flowers: Small pink-white flowers in a rounded umbel, often mixed with bulbils; true seed is rare in cultivated garlic
Stem: Tall, leafless flowering scape when present
Root: Fibrous roots below a compound bulb of several cloves
Fruit: Rarely sets true seed; propagated mainly by cloves
Flowering Period: Summer

Slender, softly hairy perennial herb with narrow, lance-shaped leaves and small, four-petalled, pale pink to lilac flowers with a notched tip, borne singly in the upper leaf axils. After flowering, long, narrow seed pods split to release cottony-tufted seeds, typical of the willowherb genus.[13]

Height: 20-60 cm

Flowers: Small, four-petalled, pale pink to lilac, notched, borne singly in upper leaf axils
Stem: Slender, softly hairy, erect
Root: Fibrous root with short rhizome
Fruit: Long, narrow seed pod releasing cottony-tufted seeds
Flowering Period: June-September

Habitat

Believed to originate in Central Asia; cultivated worldwide in temperate and subtropical climates as a garden and field crop, thriving in well-drained, sunny sites.[1]

Grows in damp meadows, ditches, streamsides and waste ground on moist soils; native to Europe and temperate Asia.[13]

Harvesting

Bulbs are lifted in mid- to late summer once the leaves have yellowed and died back, then cured (dried) in a warm, airy place before storage; young leaves and immature flower scapes ('sprouts') can be cut earlier in the season.

Parts: Leaf, Root, Young sprouts
Season: Mid- to late summer for the bulb; spring for young leaves and sprouts

The flowering aerial parts are cut in summer while in flower, and dried in a warm, shaded, airy place.[13]

Parts: Aerial parts (herb)
Season: Summer flowering period

Traditional Uses

Garlic has one of the longest continuous medicinal histories of any plant, used across many traditional systems (Ayurvedic, Chinese, Egyptian, Greco-Roman and European folk medicine) as an antimicrobial, cardiovascular and respiratory remedy, for colds and infections, and as a digestive and immune tonic. This traditional reputation is now among the most extensively clinically studied of all herbal medicines.[1, 9]

Small-flowered willowherb, along with related Epilobium species, has a Central European folk tradition as a supportive remedy for lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH) and prostatitis, and as an antimicrobial and anti-inflammatory herb for minor infections; the traditional prostate-support use is attributed mainly to its oenothein B content, though robust clinical evidence remains limited.[13]

Preparations

Fresh clove[1]

Fresh clove crushed or chopped and left to stand briefly (activating allicin formation) before eating raw or lightly cooked.

Standardised extract/powder[1, 10]

Dried garlic powder standardised to allicin content, or aged garlic extract, taken as capsules or tablets.

Infusion[13]

Dried flowering herb infused in hot water as a traditional urinary and prostate-support tea.

Dosage

Fresh clove[11]

The WHO monograph on Bulbus Allii Sativi gives an average daily dose of 2-5 g of fresh garlic (roughly one to two cloves), alongside 0.4-1.2 g of dried powder, 2-5 mg of oil and 300-1000 mg of extract as solid material. The EU herbal monograph gives no posology for fresh cloves, so WHO is the source here. Educational reference only, not a prescription.

Standardised powder extract[10, 12]

The EU herbal monograph gives, for adults and elderly, powdered herbal substance at a single dose of 300-750 mg for a daily dose of 900-1380 mg divided into 3 to 5 doses; liquid extract 110-220 mg four times daily; and, for the second indication, dry extract 100-200 mg 1-2 times daily (daily dose 100-400 mg). Garlic is CONTRAINDICATED in patients on saquinavir/ritonavir therapy. Not recommended under 18 years for the first indication. Educational reference only, not a prescription.

Infusion[14]

The EU herbal monograph gives 1.5-2.0 g of the comminuted herb in 250 mL of boiling water as an infusion, twice daily, in adults and elderly; long-term use is possible. Lower urinary tract or prostate symptoms should always be medically assessed first, and the monograph directs that a doctor be consulted if fever, spasms, blood in the urine, painful urination or urinary retention occur. Educational reference only, not a prescription.

Dangerous Lookalikes

Safety note[34, 35, 36, 37]Fatal
Dangerous Plant: colchicum-autumnale
Confused Part: Spring leaves, when foraging wild garlic (ramsons) foliage before flowering.
Confusion Context: When people gather wild garlic (ramsons) leaves in spring, autumn crocus leaves — which emerge at the same time in the same damp meadows and woodland edges — are the deadliest thing they can pick by mistake. Autumn crocus contains colchicine, a cell poison with no reliable antidote; a few leaves can kill, and poisoning is repeatedly documented from 'wild garlic' that was actually autumn crocus, progressing from stomach upset to multi-organ failure.
Distinguishing Features: Crushed wild-garlic leaves smell strongly of garlic or onion; autumn crocus leaves have NO garlic smell., Each wild-garlic leaf grows singly on its own slender stalk; autumn crocus leaves are thicker, stiffer and glossy, several clasped together from a common base at ground level, with no individual stalks., Wild garlic pulls up with a small white bulb and onion-like roots; autumn crocus has no garlic bulb.
Key Test: Crush one leaf with clean hands and smell it: a strong garlic or onion smell = wild garlic (safe); no garlic smell = do not pick it. Hands already smelling of garlic give false reassurance, so test with clean hands.

Dangerous Plant: convallaria-majalis
Confused Part: Spring leaves, when foraging wild garlic (ramsons) foliage before flowering.
Confusion Context: Lily-of-the-valley leaves emerge at the same time and in the same shady, damp woodland as wild garlic and are a classic, sometimes fatal, mix-up. The plant contains cardiac glycosides (convallatoxin) that disturb the heartbeat like an overdose of heart medicine, and there is no reliable antidote; foragers who ate leaves they took for wild garlic have arrived at hospital with a dangerously slow heart and low blood pressure.
Distinguishing Features: Crushed wild-garlic leaves smell strongly of garlic or onion; lily-of-the-valley leaves have NO garlic smell., Wild garlic has ONE leaf per individual stalk; lily-of-the-valley has a pair (sometimes three) of leaves wrapped together around a single common stalk, often purplish at the base., Lily-of-the-valley leaves are stiffer and glossier, and there is no garlic bulb underneath.
Key Test: Crush one leaf with clean hands and smell: strong garlic or onion = wild garlic (safe); no garlic smell = discard. Then check the leaves — one leaf per separate stalk (wild garlic) versus a pair of leaves sheathed around one common stalk (lily-of-the-valley).

Confusion Context: Lords-and-ladies pushes up its young leaves at the same time and in the very same damp woods as wild garlic, often mixed in with it. Every part contains needle-like calcium-oxalate crystals: biting a leaf drives them into the mouth and throat, causing immediate intense burning, blistering and swelling — occasionally enough to threaten the airway.
Distinguishing Features: Crushed wild-garlic leaves smell strongly of garlic or onion; lords-and-ladies leaves have NO garlic smell., Wild-garlic leaves have parallel veins running the length of the leaf; lords-and-ladies leaves have a branching net of veins., Lords-and-ladies leaves are arrow- or spear-shaped with two backward-pointing lobes ('tails') at the base, often glossy and sometimes dark-spotted; wild-garlic leaves are smooth ovals with no basal lobes.
Key Test: Crush one leaf with clean hands and smell: garlic or onion = wild garlic (safe); no smell = discard. Reject any leaf that is arrow-shaped with basal 'tail' lobes or has net-like (not parallel) veins — that is lords-and-ladies.
