My GF's father (62 yrs old) suffers from swollen legs (Peripheral Edema). He has serious heart issue's with mini-heart attacks everyday. Strong smells also set him off and makes his chest hurt. He eat's nitro-pills like M&M's. He says hot weather causes his legs to swell.“He works outside in construction”.
The family has been rubbing Rosemary essential oil undiluted on his legs. It brings the swelling down in a few hours and the smell does not aggravate his heart.
Hope this helps someone...
