According to the World Health Organization (WHO), the term “herbal medicines” includes “herbs and herbal materials, herbal preparations and finished herbal products that contain parts of plants, other plant materials, or combinations as active ingredients.” with the defining so-called “active ingredients” as “the ingredients of herbal medicines with a therapeutic activity where the active ingredients have been identified, and if adequate analytical methods are available, the medicinal preparation should be standardized to contain a defined amount of the active ingredients”. If it is impossible to extract and measure the exact ingredient, then the whole herbal product is considered to be one.
Studies show that over 80% of people worldwide use herbal medicines for the prevention and treatment of various conditions, to feel better, to have more energy, etc. And herbal over-the-counter drugs and supplements are commonly believed to be milder in effect and safer due to their natural origin, which is why they are often consumed by pregnant women, especially for treating colds and headaches. And that is without mentioning the use of herbs as teas, spices, or food.
However, there are very important reasons for you not to use products that contain one or another herb during pregnancy without a previous consultation with medical professionals that guide you through the pregnancy.
