Author: Akika Horie (Kampo Pharmacist) - Set of 4 books. ① All Blood Flow Problems Solved - Published March 2016 ② How to Eat to Regulate Blood Flow - Published September 2018 ③ How to Live to Regulate Blood Flow - Published November 2019 ④ Why Are You Living While Hurting Yourself? - Published July 2021 These books have been stored at home for a long time, so there are signs of use such as stains, scratches, and folds, but the inside is in very good condition. My wife read these books, improved her constitution, and underwent fertility treatments. Thanks to that, we have been blessed with many children. It's a shame to throw them away, but I don't have enough space to keep them, so I'm putting them up for sale. I plan to ship via Yu-Packet Plus, but if it's too tight, I'll send it via regular Takkyubin (home delivery service) size 60.
