For centuries in Japan, citrus peels have been added to hot bath water both for their relaxing aromatic effects and to provide ‘a body warming sensation’ after bathing. It is now understood that hesperidin, which belongs to a class of natural substances known as bioflavanoids, is an active component of citrus peel and is responsible for the body warming sensation after bathing by stimulating circulation to the skin. - Millet

Fascinating, Millet. I think I'm going to actually try this. I wonder how much citrus peel needs to be added to the bath water? I got back in the gym after a two week hiatus, and everything hurts right now. So I was thinking of a nice hot bath and finishing up a great book, "Fall of Giants" this evening. Will put some citrus peel in the water, too. If not anything else, it sure will smell good

In Japan they float whole Yuzu fruit in their baths.

Hmm.... wonder if I could substitute the Etrog I have? Was going to save the seeds, but trying to find a use for the Etrog, besides just sitting in the fruit bowl looking pretty

Okay, that's more citrus than I probably have hanging on all my trees, lol! Looks awfully pretty, though!

Laaz knows "google-foo"; he is the google-meister of pictures!

Hah, true, Marc. Maybe 6 to 7 citrus in the bath. My husband will think I've lost my marbles.

I had to search to understand:

Don't forget to invite your husband in the bath!

Just this one (that's a Ponkan mandarin next to it for size comparison):

Nice fruit!
