Hmm, I was just having a discussion with my ND about this last week. He was telling me that he hasn't been able to get the natural thyroid supplements for his patients, and I asked if it was FDA. Now I know. I emailed this link to him.
I also suspect that other natural glandulars will be on the list too. I remember reading about when/how the adrenal glandulars were first used, during the flu epidemic of 1918..and it also is talking about the big pharma drug companies making a switch to the synthetics in the 1950's, and side effects that came with it.

>>Their first claim to fame in the United States occurred with the epicemic flu virus of 1918. Respiratory infections are especially hard on the adrenal glands and fatigue them rapidly. This effect was shown by Lucke and his associates at Camp Zachary Taylor in 1919, when he found that adrenal exhaustion was present in 103 of 126 autopsied cases of mortality from the flu epidemic. In 3 other cases he even found adrenal hemorrhages and enlargement of the adrenal glands to twice their size. This means that in 106 of 126 patients who died from influenza, the adrenals were actually damaged by the infection. It is not that the adrenals were infected per se, but that the effort they made to try to restore balance to the body led them to a degree of exhaustion that was physically detectable upon autopsy (Lucke, B., et al., Archives of Internal Medicine, August 1919, XXIIII, pg. 154).
While this flu epidemic was debilitating and even killing thousands around the world, a few hundred of its victims were given a formula containing liquid adrenal cortical extracts (extracts from the adrenal cortex) combined with small amounts of thyroid and gonadal extracts. The formula was found to be unusually effective in overcoming many of the asthenic (weak) and depleted states that were so common to those afflicted with this deadly flu. It also effectively reduced the serious sequeli that usually followed this particular infection. The benefits of this adrenal cell extract formula dramatically drew attention to its practical use. The quick and uneventful recovery experienced by those taking it contrasted to the long period of recuperation normally seen in this flu epidemic. These results made many physicians aware of the possibility for recovery from less severe forms of hypoadrenia as well. It was known even in 1919 that the early functional endocrine disorders, especially adrenal fatigue, are infinitely more common and far more likely to respond to therapy than extreme endocrine diseases such as Addison’s (Harrower, ’39, pg. 17).
By the mid 1930’s, adrenal cell extracts in liquid and tablet forms were produced by several companies. By the late 1930’s, they were being used by tens of thousands of physicians. As recently as 1968 they were still being made by some of the leading pharmaceutical companies (Upjohn and Eli Lilly, among others).
However, in the early 1950’s synthetic cortisol became available. Because the synthetic hormone produced effects that seemed, at first, so much more dramatic than the effects of adrenal extracts, many physicians switched to synthetic cortisol and its derivatives to treat conditions they had previously treated with adrenal cell extracts. Unfortunately for patients, the profit margins were also more dramatic for the synthetic corticosteroids. This quickly made the synthetics the unquestionable favorite of the pharmaceutical industry. Within a few short years, the many detrimental side effects of the synthetics started appearing, but the pharmaceutical industry had made its profitable choice and would never turn back. In fact there has been a concerted effort to discredit adrenal and other cellular extracts and to remove them from the market. Luckily, these valuable cellular extracts, which provide more true benefits to your body without the damaging side effects of synthetic corticosteroids, are still available from a few sources.>>
