New, unopened] Wakan no Mori Hihatsu & GABA no Megumi, 30 days' worth Please refrain from price negotiations. Expiration date: May 2027 Please only purchase if you understand that this item has been stored at home! I purchased this on Mercari, but I am now starting blood pressure medication. A pharmacist advised me that it's best not to take this supplement in conjunction with the medication, so I am unfortunately selling it.
