For a year I have suffered from regular nausea and stomach ache, and my stomach churns (noisily) mornings and evenings. Despite blood tests and an endoscopy, the doctors are none the wiser. I've tried omitting wheat from my diet, with no success. I'm currently taking Zoton tablets, but would prefer an alternative method. Can you help?

These symptoms can be related to a lack of digestive enzymes, food sensitivities, inflammation of the digestive tract or problems with stomach valves; stress is usually an added factor. It is worth omitting dairy products from your diet for a month, to see if this leads to any improvement. Zoton tablets inhibit the gastric acid secretions in the stomach, but some acidity is needed to break down foods. Try avoiding acid-forming substances, such as alcohol, coffee, tea, aspirin, cigarettes and concentrated protein (meat, fish and eggs). Digestive problems can be complex, so analysis and advice from a naturopath or nutritionist, with a carefully thought-out programme of treatment, would have the best outcome.

My daughter has just had a large mole removed from her cheek. Any suggestions for minimising scarring?

Oil of rosa moschata from Andes rosehips is excellent for healing scars. Barefoot Botanicals (0870 220 2273, barefoot-botanicals.com) has created a blend of organic plant oils and vitamins (such as apricot kernel, carrot oil, natural vitamin E, frankincense, mandarin and sandalwood essential oils) to help accelerate healing and build new skin tissue. Apply one drop twice a day (Rosa Fina Intensive Radiance Face Oil, £21.95 for 15ml).
