Since progesterone has none of the harmful side effects of other hormones (except the alteration of the menstrual cycle if taken at the wrong time of the month), the basic procedure should be to use it in sufficient quantity to make the symptoms disappear, and to time its use so that menstrual cycles are not disrupted. This normally means using it only between ovulation and menstruation unless symptoms are sufficiently serious that a missed period is not important to you.
If a person has an enlarged thyroid gland, progesterone encourages secretion and unloading of the stored colloid and can bring on a temporary hyperthyroid state which is a corrective process. A thyroid supplement (Electrical Body recommends Detoxadine) may be used to shrink the goiter before progesterone is given.
Normal amounts of progesterone promote thyroid secretion, while a deficiency, especially when too much estrogen is present, causes the thyroid to enlarge. Some mention euphoria as a “side-effect” of progesterone usage, but euphoria is simply an indication of good physiological state. To avoid unexpected anesthesia, the correct dose should be determined by taking about 10 mg (3-4 drops) at a time, allowing it to spread into the membranes of the mouth, and repeating the dose after 10 minutes until the symptoms are controlled.
An excessive estrogen/progesterone ratio (should be 1 part to 10 parts, estrogen to progesterone), is involved in producing aggravating symptoms such thin, bluish skin. Low thyroid is one cause of excess estrogen, and when high estrogen is combined with low thyroid function, the skin can look relatively bloodless.
