One interesting fact and one bit of useful advice, courtesy the Neuroskeptic blog:
• When bees use nectar from wild Rhododendrons the honey they produce is poisonous. Not poisonous as in, "dude, you have to try this poison honey it made me see god," but poisonous as in "was once left out as a deadly trap for invading armies."
• Although, like Viagra, rhododendron honey does have cardiovascular effects, you should not ingest it as a "marital aid." If you do, you will risk both death, and ending up the subject of a funny report in a medical journal.
