Before asking a question here, please use the search feature of Reddit, Google, or another search engine to make sure your question hasn't already been asked and answered. There have been many past threads about first aid supplies to keep at home, including the thread about a week ago, and many past threads about medical books. In addition, you submitted this post twice and wrote it in an unnaturally spammy way, so it's not surprising that Reddit has already flagged this as spam and suspended your account.
