Miss N.S. writes:--For the last three weeks I have been troubled with a very bad cough It started in the first place with a cold in the head and then it got on my chest, and do what will I cannot get rid of it. I have been having honey and lemon juice, and also each morning have taken olive oil and lemon juice beaten up together, but without (apparently) any effect. I have bad coughing fits in the night and the next morning I do not feel up to much. I may say that I have not taken meat for about six years, and I try to follow the kind of diet advocated in _The Healthy Life_. I am 23 years of age and a typist in an office, which is about 4 miles from my home. I try to get out in the fresh air as much as possible to counteract any bad effects which may arise from my work. My people at home are very much opposed to my food reform sympathies and efforts. This correspondent should consult a sensible doctor about this cough and thus be on the safe side. It is unwise to allow a cough to become chronic without ascertaining the cause of it. Coughs are often due to stomach and liver trouble, as distinguished from lung trouble. In either case a salt-free diet will greatly help. Thus _Breakfast._--All fresh fruit, nothing else but fruit. Apples best. (_Not_ stewed fruit). _Lunch._--Boiled or steamed rice, done without salt; about 2 oz. cottage cheese or a poached egg; a little raw carrot, turnip or artichoke, finely grated, with dressing of fruit-oil beaten up with a raw egg. The grated roots must be well chewed; as a change they may be cut up and cooked in a casserole with very little water. _Dinner._--Potato baked in skin, with fresh butter, a little cheese, or flaked nuts, and a few plain rusks, or a saucer of P.R. Breakfast Food, dry, with cream. The honey and lemon juice should be disgarded in favour of liquorice (little bits being sucked at intervals) or of linseed tea. I have often found an obstinate cough yield to a diet which contains lactic acid buttermilk, combined with the use of the new oxygen baths. The lactic acid buttermilk can be obtained from any good dairy and should be taken in the morning fasting and at bedtime. WATER GRAPES. W.G.B. writes:--Referring to article in January number entitled "Grape juice for all," I think perhaps it would interest others besides myself if Dr Knaggs would give us his opinion on the value of what are commonly termed "Water Grapes," as compared with more expensive kinds. On the Continent the grape cure is a popular method of treatment. It is especially good for those who are anaemic and underfed as well as for those who suffer in the opposite way from over-feeding. It depends upon which condition is present as to the kind of grapes selected for the cure.
