https://youtu.be/jO3AfALckJE A Danish study published in BMJ Open reports that short, standard acupuncture sessions will significantly reduce moderate to severe menopausal symptoms.   Investigators at the University of Copenhagen using a crossover protocol administered weekly acupuncture therapy for 5 consecutive weeks to a treatment group while the controls received no treatment.  Then, the controls received the acupuncture and the initially treated subjects were merely observed.     The assessors who questioned participants about their symptoms were unaware of the treatment received.  The tabulated results showed that the acupuncture therapy significantly diminished hot flashes, sweats day and night, sleep issues, emotional symptoms, skin, and hair complaints.   If you are suffering from menopause-related symptoms and are unable to get relief from conventional Western medicine, do seek out a qualified acupuncture specialist.  Complementary and alternative therapy can be very effective.   Lund KS, Siersma V,
