A man wants some advice for his 39-year-old friend who has been diagnosed with this rare condition, a bone marrow disorder causing the overproduction of white blood cells, red blood cells, and platelets. Patients may develop blood clots (and are at higher risk for strokes and heart attacks), and in some cases the condition may lead to a form of leukaemia. As allopathic medicine only offers her a weekly phlebotomy and aspirin to thin her blood, what suggestions do readers have on ways to treat this condition holistically? It is important not to get dehydrated, so be careful with or avoid coffee, alcohol, and excessive sugar. An easy way she can check for deydration is to look at her urine; if it is darker than lager, she must drink more. To reduce the chances of clotting and stroke due to the increased red cells in the blood, she should include the following anti-ageing, anti-cancer and anti-clotting agents in her daily diet: selenium, vitamin C (ensure frequent intake during the day as it only lasts a few hours), vitamin E, all onions and garlic, anthocyanidins (the purplish part of black grapes, blackberries, bilberries, aubergine skin, etc.), and vegetable lecithin (for example, from soya). A good start could be to add currants and ground ginger to oats (with warm water, to soften), spring onion to salads, nuts for Vitamin E, and sesame seeds for selenium. Blood-thinning herbs like ginger and gingko could certainly be utilized in place of the sometimes blindness-causing aspirin.
