She addressed the Thalidomide tragedy that led to the 1962 Kefauver-Harris Amendments (the source of most of the coercive powers of the FDA) at:

She also devotes an entire chapter of Healing Our World to the FDA. While I strongly recommend purchase of the 2003 edition of the book, which has more up-to-date information and research to support the case for a separation of medication and state: an older version is online, and Chapter 6: Protecting Ourselves To Death is available at:
http://www.ruwart.com/Healing/chap6.html
The online version doesn't contain the results of her more recent study demonstrating quite convincingly that the FDA regulations killed more than 4.7 million people between 1963 and 1999, and at most might have saved fewer than 100,000.
Finally, although I don't expect she will make it a centerpiece of her campaign, because she has always respected the coalition status of the LP, and the party doesn't yet have an official position on patents, her writings on the totally non-political Advocates for Self-Government web site makes clear that she doesn't believe drug patents would exist in a free society:

I would strongly urge people who want more information on her positions on health care to go to www.askdrruwart.com (there is a search box at the bottom of the page) and browse the many answers on the topic that she has provided over the years.

At the same time, just as I welcomed Bob Barr into the LP while believing his
journey to libertarianism still had a ways to go, I give Gravel credit for recognizing that the LP is not a brand of conservatism, but in many ways is the sane
center in a world where the choice offered between the left-wing and right-wing parties is Your Money or Your Life.
