Cordyceps is a Chinese mushroom that is very effective in treating thyroid problems, particularly when nodules are present. We therefore recommend a three-month course, then observing the results.
However, be careful if you have other hormonal problems, and consult your doctor if you are taking medication.

What published research says about the remedies mentioned above, for context — the studies address material causes, while healing belongs to Allah.
The thyroid
Selenium reduces antibodies in Hashimoto's thyroiditis according to a recent meta-analysis (Thyroid, 2024) and its level is correlated with autoimmune thyroid diseases (Ann Palliat Med, 2021); iodine, selenium, vitamin D, and iron are the key nutrients for the thyroid (Hell J Nucl Med, 2017). Brazil nuts, fish, eggs, and seaweed (with caution) provide these. Precaution: do not supplement with iodine without testing (excess can worsen certain thyroiditis cases); thyroid treatments should never be stopped on one's own.
