Health care is an interesting market because for the most part it's remarkably stable. Here are five health care-related stocks with long-term growth potential, according to Morgan Stanley.

We’ve already listed Morgan Stanley’s stock winners with the best long-term growth potential, but what if you’re looking into a specific sector? Morgan Stanley’s original list of stock winners no matter what happens with the economy had a total of 42 stocks, but we're just taking a look at health care-related companies.

Health care is an interesting market because for the most part it’s remarkably stable. Whenever there is trouble with the economy, investors head for the health care stocks. In September, Morgan Stanley had actually trumpeted health care stocks because of how well they consistently perform.

Here are five stocks from Morgan Stanley’s list of 42 that are health care related.

Note: The EPS growth is the projected compound annual growth rate (CAGR) from 2011 to 2014; the P/E estimates are based on 2012 EPS expectations; and the PEG ratio refers to the price earnings to growth ratio, which is an indicator of the stock's valuation.
