People's Pharmacy: Thanks for the cheap trick for how to treat rashes

People’s Pharmacy discusses several reader-submitted remedies, including potential nutrition links to blood pressure and common, low-cost treatments for rashes. One correspondent credits daily pomegranate juice for helping reduce their systolic blood pressure from above 140 to about 125 over roughly two months, citing studies on pomegranate effects on ACE activity and on outcomes in randomized trials. The column also addresses a rash under the breast fold, saying topical milk of magnesia (magnesium hydroxide) may help; it references research on conditions such as poison ivy, diaper rash, acne and atopic dermatitis. Another reader recounts high-dose vitamin C at the start of cold symptoms; evidence suggests vitamin C rarely prevents colds, but at least 1 gram daily may shorten duration and reduce severity.
