According to Balch and Balch (2000), 3 to 4 grains of Armour
Dessicated Thyroid Tablets will raise a regular morning temperature of 96F
to the normal range, while 1 to 2 grains will raise a morning temperature of
97F to the normal range (see p450-453 of Prescription for Nutritional
Healing, 2000).  You can obtain Armour Thyroid tablets without a
prescription.
