For centuries, people have used herbs both to nourish and to heal the body. In addition to adding flavor to food, many herbs are high in antioxidant, anti-inflammatory, and antiseptic properties.

While many grocery stores sell fresh herbs, it is easy and inexpensive to grow your own at home. In fact, most herbs do well in a backyard garden or even on a sunny windowsill.

1. Basil

Fragrant and easy to grow, basil is a tasty addition to soups, sandwiches, and many Mediterranean dishes. The herb also contains oils and flavonoids that help protect the body from illness and infection.

Basil contains vitamins A, C and K, copper, manganese, calcium, magnesium, iron and helpful omega-3 fatty acids. As a medicinal herb, basil can work as anti-septic for cuts and scrapes, and it can offer relief from headaches, flatulence, and a lack of appetite.

Grow your basil plant from seed in a warm, sunny location, and keep the soil moist. An annual plant, basil is quite sensitive to cold. Indoors, keep it away from drafty windows and outdoors, cover it on days when the temperature dips below about 50 degrees. Simply snip the leaves for use.

2. Catnip

Catnip is so named because cats are attracted to it and enjoy its aroma. For people, catnip has a similar effect in that it can be used as a stress reliever by breathing it in. This is because of the presence of nepetalactone and thymol in catnip, which likewise can be used as a sleep aid or to relieve skin irritation.

The best way to use catnip is to either brew a few of its leaves for tea, or to dry the leaves and burn them while inhaling its aroma.

3. Cayenne Pepper

Cayenne pepper is usually used to add spice to meals, but it can be used as a body detoxifier as well. That’s because the primary compound in cayenne pepper is capsaicin, which while responsible for the spicy kick that cayenne pepper offers, is also responsible for boosting your body’s metabolism, improving blood circulation, improving digestion, and detoxifying the body.

Besides adding cayenne pepper to dishes, dressings, or sauces, you can also consume it directly, either in its original form or as a pill.

4. Chamomile

Known as a soothing tea, chamomile is another easy medicinal plant to grow at home. In addition to its calming properties, chamomile provides relief for an upset stomach and can ease skin irritations. Chamomile also has been used for centuries as a gentle way to calm colicky babies.

Chamomile plants prefer full sun and can grow to about 18 inches tall. German chamomile is easy to grow from seed, and after the first season, the plants self-sow freely.

The pretty daisy-like flowers appear within six weeks of planting, allowing two plantings in one outdoor growing season. German chamomile prefers a cool climate, full sun and neutral to slightly acidic, well-drained soil.

Place the blooms in a warm, dark place to dry.

5. Echinacea

Known for its healing properties for treating the common cold, Echinacea (also known as coneflower) is useful both as a tea and in a tincture form.

The purple plant grows to about two feet tall and requires full sun. Echinacea is biennial and flowers only in its second season.

6. Fennel

Often recognized for its licorice-like flavor, fennel is a hardy perennial that’s both a culinary favorite and a medicinal treasure. It’s known to have diuretic, pain-reducing, and anti-inflammatory effects, and is often used for digestive problems like bloating, gas, and stomach cramps.

Fennel is quite easy to grow and prefers full sun and fertile, well-drained soil. It can grow quite tall, so be sure to give it plenty of room. The bulb, foliage, and seeds of the fennel plant are all edible and beneficial to health.

7. Feverfew

Feverfew, as the name suggests, has historically been used as a fever reliever. It can also be used to alleviate pain from arthritis and migraine headaches or to prevent a migraine headache from developing further when it begins.

Tie several stalks of feverfew into a bundle, and then dry for a week outside. You can then brew it as tea, or consume it directly in the form of capsules. As an added benefit, it’s an effective insect repellant too. Just take note that feverfew can also cause digestion irritation as a side effect, so be aware.

8. Ginger

While ginger is often considered a spice, it’s actually a flowering plant whose rhizome (underground stem) is used for its culinary and medicinal properties. Known for its distinctive flavor, ginger is also well-regarded for its anti-nausea, anti-inflammatory, and antioxidant effects. It can help with issues such as motion sickness, morning sickness, inflammation, and even lower cholesterol levels.

Ginger prefers warmer climates but can be grown indoors. It’s grown from the rhizome, which can be planted in a pot with rich, well-draining soil. Allow the ginger plant to mature before harvesting, which generally takes about 8-10 months.

9. Goldenseal

Goldenseal is a natural antiseptic that is effective for diarrhea and improving digestion. It is also used to treat pneumonia, liver problems, urinary tract infections, chronic fatigue syndrome, and many other disorders.

This is because it contains a plant alkaloid called berberine, which has been used as a natural healing medicine all over the world for thousands of years, beginning in China and India. Just be aware that it’s not considered safe for children, including unborn children, so pregnant women should avoid it as well.

You can use fresh flower buds to make a tea that helps prevent and treat cold and flu symptoms. Making a tincture involves steeping the flower buds, roots, or both in pure, concentrated alcohol for four to six week weeks, and then removing the liquid.

10. Holy Basil

Different from the common culinary basil, Holy Basil, or Tulsi, is an aromatic plant that’s held sacred in Hindu tradition and widely used in Ayurvedic medicine. The herb is celebrated for its adaptogenic properties, helping the body resist physical, chemical, and environmental stressors. It is often used to promote mental balance, improve digestion, and support the immune system. Some research even suggests it has antimicrobial and anti-diabetic effects.

11. Lavender

Even the fragrance of this lovely herb helps people feel calmer and more relaxed. Lavender also eases the pain of cuts and bruises and functions as an antiseptic when applied topically.

Lavender grows best in dry, well-drained soil with full sun exposure. It requires little to no fertilizer and adequate air circulation. Keep safe from strong winds.

Lavender can help treat digestive problems, bad breath, headaches, toothache, nausea and vomiting. Adding some dried lavender to your bath water can help alleviate stress as well as insomnia.

12. Lemon Balm

A relative of mint, lemon balm (Melissa officinalis) has been a favorite of herbalists for more than 2,000 years. The versatile herb is used to treat anxiety, insomnia, insect bites, upset stomach, wounds, and herpes.

Lemon balm is easy to grow from seed, and it can grow up to two feet high. The plant prefers a cool climate with fertile, moist soil and tolerates an acidity range from pH 5 to 7.8. This plant can be invasive, so be sure to prune off the flowers before they go to seed if you don’t want it to take over your garden.

Fresh lemon balm leaves make a refreshing tea either hot or iced.

13. Marjoram

Marjoram is a delicate herb that is often used in cooking, but it also has potent medicinal qualities. Traditionally, it has been used for digestive issues such as flatulence, stomach cramps, and constipation. Furthermore, marjoram has anti-inflammatory properties and can soothe muscle spasms and headaches.

Grow marjoram in a warm, sunny location, ideally in well-drained soil. It does well as a potted plant, which makes it an ideal herb to grow indoors during the colder months. The leaves can be harvested as needed for both culinary and medicinal use.

14. Oregano

If you enjoy Italian dishes, you probably like the taste of oregano. This flavorful and aromatic herb has antibacterial, antioxidant, antimicrobial, and anti-inflammatory properties. It is rich in vitamins A, C, E, and K ad well as fiber, manganese, iron, calcium, magnesium, niacin, zinc and omega-3 fatty acids.

Oregano eases discomfort from the common cold, muscle pain, vomiting, acne, bronchitis, asthma, toothaches, stomach bloating, headaches and menstrual cramps.

You can grow oregano in raised garden beds or in containers that have well-drained soil and that receive full sun exposure. Be careful not to overwater this medicinal herb.

15. Parsley

Often used as a plate decoration in restaurants, parsley is loaded with nutrients, including folic acid and vitamins A, C, B-12, and K. It can be used to treat urinary tract infections, kidney stones, constipation, jaundice, flatulence, indigestion, colic, coughs, asthma, osteoarthritis, and high blood pressure. It also works well to fight bad breath.

Parsley, which grows well in a small garden area, prefers partial shade and moist, well-drained soil.

16. Peppermint

Menthol gives this hardy perennial herb its spicy-sweet aroma and taste. Merely sniffing a sprig of peppermint can help alleviate the nausea and vomiting that is associated with motion sickness.

Sipping peppermint tea can calm nervous tension and an upset stomach. It also helps soothe headache pain.

It is a good idea to grow this fast-spreading plant in containers. Its stalks can grow up to three feet tall, and it spreads horizontally readily. Peppermint prefers full sun and moist, well-drained soil. Harvest the leaves as they mature and then let them dry in a warm, dark place.

17. Rosemary

This aromatic medicinal herb has antioxidant and anti-inflammatory compounds as well as phytonutrients, iron, calcium, essential fatty acids and vitamin B6. It is useful in treating headache pain, the common cold, indigestion, muscle pain and neuralgic conditions. Long called “the herb of remembrance,” rosemary also is thought to enhance the brain’s cognitive function.

Rosemary grows best in a sunny location with well-drained, sandy or gravelly soil with neutral to alkaline conditions. It is a perennial, but water logging and/or frost will challenge its health.

You can grow rosemary in a pot or container, or you can plant is as an attractive hedge in your garden. Pinch the fragrant needles for use in a tea or as an ingredient in cooking.

18. Sage

The Latin genus name for sage is “salvia,” which means, “to heal.” This easy-to-grow plant has been used for centuries to treat loss of appetite, stomach pain, heartburn, excessive sweating, cold sores, gum disease, gingivitis, menstrual cramps, and asthma.

Sage grows well in well-drained, fertile soil with plenty of sunlight. It boasts thick, long grey-green leaves that can be used in cooking.

19. St. John’s Wort

This bright yellow flowering plant is usually associated with its antidepressant properties, thanks to its active ingredient hypericin, which is thought to impact certain mood-regulating neurotransmitters in the brain. Beyond its use for depression, St. John’s Wort is also used for conditions such as menopausal symptoms, attention deficit-hyperactivity disorder (ADHD), and obsessive-compulsive disorder (OCD).

St. John’s Wort grows well in full sun to partial shade and prefers well-drained soil. Be careful, as it can become invasive if not regularly pruned. This plant’s vibrant flowers can be dried and used to make a mood-boosting tea or tincture.

20. Thyme

As a strong antiseptic, this medicinal herb is useful for treating coughs, congestion, flatulence and indigestion. Thyme is easy to grow in a sunny location and can survive both summer heat and winter frost.

You can use thyme in many ways:

• As a gargle to treat bad breath and mouth sores.
• As a poultice on the neck to reduce throat pain.
