Garlic (Allium sativum) — Common Garlic, Stinking Rose
Materia Medica
Family: Amaryllidaceae
Common names: Garlic, common garlic, stinking rose
Part used: Bulb (cloves)
Growth habit: Bulbous perennial grown as an annual
Primary tradition: Global culinary and medicinal use; classical European, Ayurvedic, and Chinese traditions
Actions & Energetics
Warming, pungent, and drying. Traditional actions include antimicrobial, cardiovascular tonic, carminative, and expectorant. The characteristic pungency comes from sulfur compounds released when the clove is crushed. Energetically considered heating and moving in multiple traditions.
Botanical Description
A bulbous plant with long, flat green leaves and a papery white bulb composed of individual cloves. It is cultivated worldwide and rarely sets seed under cultivation. The bulb is the primary part used both culinarily and medicinally.
Name Confusion & Look-Alikes
True garlic is distinct from wild garlic or onion relatives. Culinary garlic bulbs are readily identified by their characteristic odor and clove structure. Do not confuse with ornamental alliums.
Traditional Indications
Long history of use for respiratory infections, digestive support, and as a general tonic. Classical and folk traditions worldwide associate it with cardiovascular health, colds, and as a protective food. Culinary use is nearly universal.
Preparations & Dosage
Fresh crushed cloves, infused oil, tincture, or aged extracts. Culinary amounts are common; medicinal doses of raw garlic are typically 1–2 cloves daily or equivalent in prepared forms. Standardized extracts are used in modern research.
Classical Formulations
Garlic appears in numerous traditional formulas across cultures for respiratory and circulatory support. No single universal classical formula defines its use; it is more often a household and culinary medicine.
Constituents
Organosulfur compounds (alliin, allicin, ajoene, and others), flavonoids, and selenium. Allicin forms when the clove is crushed and is responsible for much of the antimicrobial research interest. Composition varies with preparation and storage.
Modern Research
Extensive research on cardiovascular markers, antimicrobial activity, and immune modulation. Human trials show modest benefits for blood pressure and cholesterol in some populations. Antimicrobial effects are well documented in vitro. Results vary by preparation type.
Adverse Effects
Breath and body odor are common. Raw garlic can cause digestive upset or heartburn in sensitive individuals. Topical use may cause skin irritation. High doses of supplements may increase bleeding risk.
Interactions & Contraindications
May potentiate anticoagulant medications. Avoid high-dose supplements before surgery. Generally safe as a food. Caution with blood-thinning drugs.
Pregnancy & Breastfeeding
Culinary amounts are generally regarded as safe. High-dose medicinal use during pregnancy lacks sufficient safety data.
Habitat & Cultivation
Cultivated worldwide in temperate climates. Prefers well-drained soil and full sun. Planted in fall or early spring depending on climate. Requires a cold period for proper bulb formation in many varieties.
Propagation
Propagated exclusively by cloves. Plant individual cloves point-up in fall for spring harvest in most temperate zones.
Harvesting & Drying
Harvest when leaves begin to yellow and dry. Cure bulbs in a dry, airy place for several weeks before long-term storage. Store in cool, dry conditions with good airflow.
Food Use
One of the most widely used culinary herbs and vegetables worldwide. Used fresh, roasted, pickled, or powdered in virtually every cuisine.
History, Folklore & Spiritual Use
Garlic has a long history as a protective food in European, Mediterranean, and Asian traditions. Folklore associates it with warding off illness and negative influences. It remains a staple of both kitchen and herbal practice.
Materia Medica Summary
Garlic (Allium sativum) is a globally cultivated bulb with a dual culinary and medicinal reputation for antimicrobial and cardiovascular support. The sulfur compounds released on crushing are central to both its flavor and research interest. Educational information only.
