Garlic (Allium sativum) is a perennial plant of the Amaryllidaceae family, characterized by a pungent odor and strong taste. It has been known and used in various regions of the world for a long time. Garlic originated in Central Asia, where it was cultivated several millennia ago. The plant is closely related to other bulbous plants – onions, leeks, and chives.
Most Popular Varieties
Garlic is divided into two main groups: hardneck and softneck. Hardneck garlic (Allium sativum var. ophioscorodon) cloves are arranged around a hard stem; they are often grown in cooler climates and have a stronger taste. Softneck garlic (Allium sativum var. sativum) does not have a hard stem, is easier to braid, and is popular in warmer regions. In Lithuania, local varieties such as 'Lithuanian Winter' and 'Lithuanian Summer' are most commonly grown, while globally known varieties include 'Music', 'California Early', and 'Purple Stripe'. Hardneck varieties are better suited for winter, while softneck varieties are better for longer storage.
Nutritional Value
Garlic is a low-calorie vegetable – 100g contains about 140 kcal. It is rich in vitamin C, B vitamins (especially B6), and minerals – potassium, selenium, manganese, calcium, and phosphorus. The main macronutrients are carbohydrates (~33g/100g), proteins (~6g/100g), and low fat content. Its greatest biological value comes from sulfur compounds, such as allicin, which is formed when garlic is crushed, as well as flavonoids and antioxidants.
Health Benefits
Garlic is valued for its potential immune-boosting effects – its active compounds can stimulate the activity of white blood cells. Due to allicin and other sulfur compounds, garlic has antibacterial and antiviral properties. Studies show that regular garlic consumption can help maintain normal blood pressure and cholesterol levels, contributing to the protection of the cardiovascular system.
Culinary Uses
Garlic is consumed fresh, baked, dried, or pickled. Fresh garlic is added to salads, spreads, and sauces. Baked or stewed garlic is excellent in soups, stews, and meat and vegetable dishes. Dried garlic is used in spice blends. Popular dishes include garlic bread, aioli sauce, pesto, and various pasta and vegetable dishes. It pairs well with parsley, basil, oregano, rosemary, and black pepper.
Cultivation and Care
Garlic requires light, loose, fertile soil, and grows best in neutral or slightly acidic pH soils. The plant prefers a sunny location and sufficient moisture but does not tolerate waterlogging. It is planted in autumn (winter varieties) or spring (summer varieties), using cloves, 4–6 cm deep, 10–15 cm apart. Care includes weeding, watering during drought, and fertilizing with organic fertilizers. Common diseases include powdery mildew, rust, and bacterial rot; pests include onion flies and nematodes.
Harvesting and Storage
Harvesting takes place when garlic leaves begin to yellow – in mid-to-late summer. Dig carefully to avoid damaging the bulbs. After harvesting, garlic is dried in a well-ventilated area for 2–3 weeks until the leaves and stems are dry. Cool, dry, dark places (0–4 °C, 60–70% humidity) are suitable for storage. Bulbs can be braided or stored in baskets. It is important to protect them from moisture and cold to prevent rot or sprouting.
Garlic in Traditional Medicine
In folk medicine, garlic is used in various ways – from infusions to ointments. Traditionally, it has been used to boost immunity, alleviate cold symptoms, and promote digestion. Popular recipes include garlic infusions with honey, milk, garlic oil, and garlic inhalations. Excessive amounts can cause stomach irritation, so moderate consumption is recommended.
Industrial Applications
Garlic is widely used in the food industry to produce spices, sauces, spreads, and marinades. In the pharmaceutical and supplement industries, garlic extracts, powders, capsules, and oils are made from it. Non-traditional uses include natural pest control for gardens and fragrances in cosmetics.
Potential Negative Properties
For some people, garlic can cause allergic reactions – rashes, itching, and respiratory problems. It can interact with blood-thinning medications, so it is advisable to consult a doctor when taking such medications. In larger quantities, it can irritate the digestive tract, causing heartburn, bloating, or bad breath.
