Another cause of intolerable itching (especially vaginal or vulval itching: BV, Bacterial Vaginitis/Bacterial Vaginosis) can be a yeast/fungal infection/Candida/Thrush which may have resulted from taking penicillin or some other antibiotic which has altered the balance of your gut flora. Alternative home remedies for this variously include wearing cotton underwear and trying to improve the balance of the vaginal flora by eating less sugar, by eating probiotic yogurt or by applying the yogurt directly to the vagina. By a happy coincidence, eating dairy yoghurt also reduces excess weight by increasing the excretion of fat from the body via the faeces. See http://www.bbc.co.uk/sn/humanbody/truthaboutfood/slim/calcium.shtml where you will read: "a high calcium intake increases the excretion of fat in the faeces". – In fact, the researchers found that twice as much fat was excreted on a high calcium intake as on a low calcium intake – and this was independent of calorie intake. – They also found that dairy calcium (they suggest eating yoghurt) is a particularly good source for this extra calcium.
