For months, the skin on my cheeks has been very red and dry. I eat healthily and follow a careful skincare routine. Can you recommend anything?

It sounds as if you are dehydrated, which is more of a problem in winter, due to central heating, wind and rain. Moisturisers alone are not the answer - take three dessertspoons of flaxseed oil and drink eight glasses of still or filtered water a day. If there is a build-up of dead cells, moisturisers will not be absorbed. Gentle exfoliation, such as the Sher System's multiple rinse technique, will not damage delicate skin and their natural protective make-up keeps moisture sealed in.

I had a stroke a while ago and am on medication to reduce blood pressure. Is there a safe natural remedy?

Natural medicine can safely decrease the odds of another stroke, but should be part of a programme monitored by a medical doctor in partnership with an experienced alternative practitioner. Changes in diet and lifestyle take time and effort, but do pay off: stopping smoking, losing weight, increasing exercise and learning to relax can be crucial. Cut down on animal fats (including dairy) and protein. Instead, eat lots of fruit and veg - full of fibre and nutrients to lower blood pressure and cholesterol levels. Walnuts, soya beans and canola oil contain alpha-linoleic acid, which is thought to reduce the formation of blood clots. Garlic thins the blood and reduces cholesterol, and high levels of vitamin C can protect against stroke. Supplements of vitamin E, omega-3 fatty acids and co-enzyme Q10 help open and repair the arteries, and strengthen the heart; and ginkgo improves circulation of blood through the brain.
