Hi, sorry to bother you, but I have some questions about propolis, and you seem to be rather keen on the subject. All I know is that it is brown-greenish, sticky, and bees use it to fill gaps, and holes. Why would health food people be interested in it??? What benefits come from eating it?? how does it taste and lastly is it expensive to purchase (I'm not keeping bees just yet) Thanks for your time.. /sb
