1. Children
-The immature fruit of black elderberry contains toxins. Although mature fruit is usually used in the process of processing into powder, children's physical functions are not fully developed and mature, and their detoxification function is relatively weak. Especially for infants and young children under 2 years old, their digestive and immune systems are still fragile. Eating black elderberry powder may cause gastrointestinal discomfort, allergies, and other adverse reactions, so it is generally not recommended to consume it.
2. Pregnant and lactating women
-At present, although there is not enough evidence to show the adverse effects of black elderberry powder on pregnant women and fetuses, the safety of these ingredients during pregnancy and lactation has not been fully determined due to the possible presence of some bioactive ingredients. To avoid potential risks such as adverse effects on the fetus or infant, pregnant and lactating women are advised to avoid consuming black elderberry powder.
3. Patients with autoimmune diseases
-Black elderberry powder has the effect of enhancing immunity, which is an advantage for healthy individuals. However, for patients with autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, etc., the immune system is already overactive, and consuming black elderberry powder may further stimulate the immune system and worsen the condition. For example, in patients with rheumatoid arthritis, excessive stimulation of the immune system may lead to worsening joint inflammation, more severe pain and swelling.
4. Individuals with allergies
-Some people may be allergic to black elderberry and may experience allergic reactions after consuming it. Allergic symptoms may include itching of the skin, rash, difficulty breathing, swelling of the mouth and throat, etc. Even if there is no history of allergies before, caution should be exercised when consuming black elderberry powder for the first time. Try a small amount first and observe for any allergic reactions.
5. People who are currently taking specific medications
-Black elderberry powder may interact with certain medications. For example, it may affect the efficacy of immunosuppressants. If taking immunosuppressants (such as cyclosporine, tacrolimus, etc.), consuming black elderberry powder may interfere with the therapeutic effect of the medication, as the immunomodulatory effect of black elderberry powder may weaken the inhibitory effect of immunosuppressants on the immune system. In addition, there may be interactions with some hypoglycemic and antihypertensive drugs, so before consuming black elderberry powder, it is recommended to consult a doctor or pharmacist to ensure safety.
