I recently read this book by dr Daniel Keown "the spark in the machine or How science of acupuncture explains the mysteries of western medicine" published in 2014.
To be honest I recommend every health practitioner and medical field related person to read this book. It's comprehensive and to the point.
It explains acupuncture through embryology and fascia and bio-energetic nodules. It makes acupuncture a little less weird for medical staff who have had no training with other traditional medicine.
