Ten of the most widely used healing herbs are aloe vera, ashwagandha, chamomile, cinnamon, dill, ginger, turmeric, ginseng, rosemary and thyme. Some, like ginger for nausea and aloe gel for minor burns, have reasonable evidence behind their traditional uses; others are mainly supported by tradition and early lab research. All of them can be enjoyed safely in normal food amounts, but concentrated supplements are a different matter and can interact with medicines, so check with a doctor or pharmacist first.
Below is a realistic look at what each herb is used for, what the evidence suggests, and the cautions that often get left out.
How people use medicinal herbs
An herb can be the leaf, flower, seed, bark or root of a plant. People take them in several forms, and the form changes the dose a lot.
- Culinary use: fresh or dried in cooking. Doses are small and generally very safe.
- Teas and infusions: steeping leaves or roots in hot water. Gentle and easy to control.
- Capsules, powders and extracts: concentrated doses, sometimes standardized to an active compound. More likely to have effects, and side effects.
- Topical gels and oils: applied to skin or scalp. Always patch-test first, and dilute essential oils.
In the US, herbal products are sold as dietary supplements, which do not need FDA approval for safety or effectiveness before they go on sale. Quality varies, so look for third-party testing seals such as USP Verified or NSF Certified.
A note on kratom
Kratom, a tree leaf from Southeast Asia, is often mentioned alongside herbal remedies. Supporters say kratom can help improve energy and focus at low doses, and some people use it for pain. It is, however, a controversial substance: the FDA has not approved it for any medical use and has warned about risks including dependence, liver injury and dangerous interactions with other drugs. Its legal status also varies by state and city. Anyone considering it should talk to a doctor first, especially if they take other medications.
10 healing herbs and their benefits
1. Aloe vera
The clear gel inside aloe leaves is a popular home remedy for sunburn, minor burns and dry skin, and some studies support its soothing effect on mild burns. Taking aloe by mouth is less straightforward: the yellow latex just under the skin is a strong laxative, and the FDA removed aloe from over-the-counter laxatives in the early 2000s over a lack of safety data. Stick to topical gel unless a doctor advises otherwise.
2. Ashwagandha
A key herb in Ayurvedic medicine, ashwagandha is mainly taken for stress and sleep. Several small clinical trials suggest it may modestly reduce perceived stress, but studies are short and vary in quality. There have been reports of liver injury with ashwagandha supplements, and it may affect thyroid hormone levels. It is generally not recommended during pregnancy.
3. Chamomile
Chamomile tea is a classic bedtime drink, used for relaxation, mild anxiety and an unsettled stomach. Evidence is limited but it is gentle for most adults. People allergic to ragweed, daisies or related plants may react to it, and it may interact with blood thinners such as warfarin.
4. Cinnamon
Cinnamon has been studied for its effect on blood sugar in people with type 2 diabetes, with mixed results: some trials show small improvements and others show none. It is not a substitute for diabetes medication. Common cassia cinnamon contains coumarin, which can harm the liver in large amounts, so heavy supplement use is not advised; Ceylon cinnamon has much less.
5. Dill
Dill is mostly a culinary herb, used with fish, potatoes and pickles. Traditionally, dill seed has been used for gas and indigestion, and dill water was once a common remedy for colicky babies. Research in people is limited, so think of dill as a flavorful, low-risk way to add variety to a healthy diet rather than a treatment.
6. Ginger
Ginger has some of the better evidence among kitchen herbs, particularly for nausea, including morning sickness and motion sickness. Some studies also suggest mild benefits for menstrual cramps and joint pain. In supplement doses it may increase bleeding risk with blood thinners, and pregnant women should check doses with their doctor.
7. Turmeric
Turmeric’s main compound, curcumin, has anti-inflammatory properties in lab studies, and some trials suggest it may ease osteoarthritis pain. Curcumin is poorly absorbed on its own, which is why supplements often add black pepper extract. Rare cases of liver injury have been linked to turmeric supplements, and it may not suit people with gallbladder problems or those on blood thinners.
8. Ginseng
Asian ginseng (Panax ginseng) and American ginseng have long histories in traditional medicine for energy and mental focus. Some studies suggest small benefits for fatigue and blood sugar, but results are inconsistent. Ginseng can cause insomnia and headaches and may interact with warfarin, diabetes medications and some antidepressants.
9. Rosemary
Rosemary is a staple of Mediterranean cooking. Its aroma has been linked in small studies to alertness, and rosemary oil has drawn interest as a scalp treatment for thinning hair, though the research is early. Dilute the oil before applying it to skin, and avoid large medicinal doses during pregnancy.
10. Thyme
Thyme contains thymol, a compound with antimicrobial properties that is used in some mouthwashes. Thyme has also been used traditionally for coughs, and herbal cough preparations containing thyme are sold in parts of Europe. As a cooking herb it is very safe; concentrated thyme oil should not be swallowed.

Growing and cooking with healing herbs
The easiest and safest way to enjoy most of these plants is in the kitchen. Rosemary, thyme and dill grow well in pots on a sunny windowsill or balcony, and aloe vera is a forgiving houseplant that needs little water. Fresh ginger keeps for weeks in the fridge and can be grated into tea, stir-fries and soups. A pinch of turmeric and black pepper in lentils or rice, cinnamon on oatmeal, and a cup of chamomile before bed are simple habits that add flavor and variety without the risks of high-dose supplements.
How to use herbs safely
- Tell your doctor or pharmacist about every herb and supplement you take, especially if you use blood thinners, diabetes or blood pressure drugs, antidepressants or thyroid medication.
- Start with food and tea before moving to concentrated supplements.
- Take one new product at a time so you can tell what is helping or causing side effects.
- Be extra careful during pregnancy, while breastfeeding, before surgery, and when giving herbs to children.
- Do not stop prescribed treatment in favor of herbs without medical advice.
