The only thing that can treat hypothyroidism is replacement thyroid medications, such as T4 medications containing levothyroxine (brand names include Synthroid, Levoxyl, etc), T3 medications containing Liothyronine (brand name
Cytomel) and desiccated hormones that contain, both T4 and T3 (these include Armour, NatureThroid, WP, etc).
Although there are plenty of articles online about "curing" Hashimoto's, there is no real cure.
