I had a bout of scalp psoriasis and dunked my head several times in the water. I didn’t have any more flare-ups again for nearly four months.
On the way back to the United States on the plane, we met a woman who flies to Iceland every three months just to go to the Blue Lagoon to treat her eczema. Now I buy the Blue Lagoon shampoo and conditioner online, and my scalp psoriasis has not recurred for nearly three years.
Researchers at the University of Iceland have studied the effect of exposure to the geothermal seawater together with exposure to narrowband ultraviolet B light (Photodermatology, Photoimmunology and Photomedicine, February 2014). Although narrowband UVB exposure is a standard treatment for psoriasis, they found that bathing in the Blue Lagoon in addition to light exposure worked faster and produced longer-lasting remissions than UVB exposure alone.
I drink about a half-cup of pure tart cherry juice every night before bedtime. Even after getting up to visit the bathroom, I go right back to sleep.
We would worry about someone your age taking melatonin pills because they can increase the risk for fracture (Age and Aging, November 2016). Tart cherry juice seems unlikely to cause dizziness or grogginess, however, because the dose of melatonin is low. You might have hit upon the best sleep aid for you.
Readers who are interested in tart cherry juice and other natural approaches to overcoming insomnia may wish to consult our newly revised Guide to Getting a Good Night’s Sleep. This online resource is available in the store at PeoplesPharmacy.com.
Q. You have written that some people stop a migraine by eating Chinese hot-and-sour soup. You implied that the benefit might be from capsaicin, the compound that gives hot peppers their kick.
While hot-and-sour soup does a great job at clearing the head and sinuses, it does not normally contain chili peppers. The “hot” in this soup comes from rice vinegar and white pepper.
Some American-style Chinese restaurants may use dried chilies or black pepper, but the standard is white pepper.
Chilies and white and black pepper come from different species. It may not matter so long as it works, but we should know the difference.
