Cautions

Cold and salty: not for Spleen–Stomach cold deficiency with poor appetite and loose stools. It is high in iodine, which matters for anyone with hyperthyroidism, autoimmune thyroid disease or a thyroid nodule under investigation, and for anyone taking thyroid medication — tell the prescribing physician before using it for any length of time.

Contraindicated in pregnancy: Not a classical prohibition, but the iodine load matters in pregnancy — avoid sustained use except under practitioner and physician supervision
