Is it forbidden to take a treatment extracted from the thyroid gland of a cow that was not slaughtered in the Islamic way, knowing that it will be thoroughly cleaned, dried, and crushed?

It is permissible to be treated with a thyroid gland from a cow slaughtered according to Islamic law if medical professionals determine its benefit. However, if it was not slaughtered according to Islamic law, it is considered carrion and impure, and it is not permissible to be treated with it through eating or drinking. Furthermore, it is not permissible to use it for purposes other than eating and drinking, as pure alternatives are available.
