Echinacea is a widely used herbal supplement that has been safely consumed for up to 10 days. It is available in various forms, such as extracts, tinctures, tablets, capsules, and ointments. It can also be found in combination with other herbs, vitamins, and minerals that help to strengthen the immune system. The combination of these active ingredients is responsible for the beneficial effects of echinacea, although research suggests that the aboveground part of Echinacea purpurea is the most effective. Different products use different parts of the echinacea plant, so the effectiveness of echinacea may vary from product to product.
It is important to choose a high-quality echinacea supplement and use it as soon as possible during a cold, with multiple doses per day for the first few days. Despite concerns that echinacea may be dangerous for pregnant or breastfeeding women, evidence suggests that its use during pregnancy does not increase the risk of birth defects or other pregnancy-related health problems. A study of 95 people with early cold and flu symptoms (such as runny nose, itchy throat, and fever) found that those who drank several cups of echinacea tea every day for 5 days felt better sooner than those who drank tea without echinacea. However, approximately 10% had no echinacea at all; half were mislabeled as to the type of echinacea in the product; and more than half of the standardized preparations did not contain the amount of active ingredients listed on the label. So, can you take more than one type of echinacea supplement at a time? The answer is yes. You can take multiple types of echinacea supplements simultaneously, such as capsules, tablets, and tinctures.
However, it is essential to consult your healthcare provider before taking any supplements to ensure that they are safe for you.
