It is best not to use ichthyococcus combination during lactation. The main ingredients of ichthyococcus combination are ichthyococcus, scutellaria, panax quinquefolium, forsythia and honeysuckle, all of which are sweet-tasting, slightly bitter and astringent drugs to lower fire, mainly for sore throat, acute pharyngitis, tonsillitis and other wind-heat syndromes. If you get these diseases you can drink more water, take good rest and strengthen nutrition, because there is no exact guidance that says that ichthyococcus combination can not be applied during lactation, but pregnant women should use caution, and adults must be taken under the guidance of a physician. If you take fishy herb combination during breastfeeding, it will pass through the blood-milk barrier and be ingested by the baby, which may have certain effects on the baby.
