Better than storing html, store a Textile format which is easy readable and similar to plain text when not rendered, but which renders as valid html.

You can use

for beeing able to choose if you want to store the markup as Textile, Markdown or BBCode.

The Textile format allows the biggest flexibility and you can also use html elements in it, but you can create with its features headings, lists of different formats, tables with many settings, links, images, and many other things.
