Thank you for viewing. This is a set of 17 packets of Ryukyu Shugo Densetsu, said to be effective for hangovers. The expiration date is October 2027 for all packets. I originally purchased several packs of 6 packets each on Amazon, but I stopped drinking, so I am selling the remaining 17 packets. Although the packets have already been opened and some are peeled, I will also include the large bag that the 6-packet packs came in, so you can see how to use it and the ingredient list.
