To help treat hyperthyroidism, there are natural remedies that can be taken alongside medication, among which onion can be mentioned. Indeed, onion is very effective in helping to treat hyperthyroidism, and it is found in different forms, the most effective being the capsule.
A person suffering from hyperthyroidism generally experiences irritability, anger, and sometimes even tachycardia, so it is advisable for them to drink linden herbal tea.
Gromwell, taken as an infusion or in capsule form, will also be a very good ally.
Finally, an intake of antioxidants such as selenium and zinc will be important for treating the condition.
What the science says: thyroid
Here is what published research says about the remedies mentioned above, for the sake of insight — the studies concern 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 them. Precaution: do not supplement with iodine without testing (excess can worsen certain thyroiditis cases); thyroid treatments should never be stopped on one's own.
