Does comfrey oil use much to have side effect to the baby

If used too much, it usually has side effects on babies. Arnebia

oil contains a more irritating taste. If inhaled by babies, it may stimulate respiratory mucosa, resulting in cough, runny nose and other discomfort symptoms. Secondly, using too much Arnebia oil will cause certain irritation to the skin, and even induce allergic reactions, causing redness, swelling and pain in local skin. In addition, if the oil is excessively absorbed by the body through the skin, it will usually lead to an increased burden on liver and kidney function, which will increase the risk of abnormal liver function and kidney function in infants.
