Herbal Teas – Support, Not Cure: Nutritionist Explains How to Avoid Harm from Medicinal Plants
Medicinal herbs can be a useful complement to therapy but cannot treat serious diseases. Nutritionist and pharmacist Alona Pletneva highlights differences between self-collected and pharmacy herbs, emphasizing individual reactions and quality control.
Many people consider medicinal herbs a safe alternative to drugs, but they have contraindications and their effectiveness depends on how they are used. Medical nutritionist and pharmacist Alona Pletneva explains how to choose wisely.
According to Pletneva, herbal mixtures can be a helpful addition to therapy but are not a cure for serious illnesses. "Herbs are like a support tool – they don't directly treat diseases. If there's something serious like bronchitis or pneumonia, we won't treat that with herbs. But as a supplement, it works," she says. She adds that reactions to herbs vary greatly: some people need only a small dose to feel an effect, while others hardly notice it. Therefore, when using herbal teas, tinctures, or preparations, it is important to follow manufacturer recommendations and start with minimal doses.
Consumers today have access to various forms of herbal products: dried herbs for brewing, tinctures, dietary supplements, and tablets. The choice depends on the desired effect as well as the person's age, health status, and individual characteristics. Pregnant women, nursing mothers, and parents of young children should be especially cautious, as not all plants are suitable for these groups.
Among the most common medicinal herbs, Pletneva mentions valerian, mint, lemon balm, and chamomile – typically used for relaxation and sleep improvement. Bearberry, parsley leaves, dill, and birch buds and leaves support the urinary system. Beneficial compounds can also be obtained not only from teas and infusions; many plants can be eaten fresh or used as spices. "Wild plants can be consumed not only as teas but also fresh. This will have an even stronger effect because fresh plants contain more bioactive substances," the nutritionist explains.
She also addresses the quality of raw materials. Pharmacy herbs are controlled at every stage – harvesting, drying, and packaging – whereas self-collection carries risks of mistakes. It is crucial not only to correctly identify the plant but also to collect it under suitable conditions to avoid mold and other contaminants. The ecological cleanliness of the collection site must also be considered. "And most importantly – don't make mistakes, because we have similar plants, and you can easily pick one instead of another. That's why you must be sure what you are collecting. If you are not sure, bring a herbalist who can show, point out, explain, and help you start," says Pletneva.
Medicinal herbs can be a useful part of everyday health care, but they should be used consciously, considering possible contraindications and without abandoning medical help for serious diseases.
