I have had a damaged right hip joint for 30 years, and have managed the discomfort with exercise and diet, but the pain is now increasing with age. Are there any supplements or foods I should take?

Arnica gel is very soothing and could be applied to your hip several times a day; Devil's Claw tincture can be taken internally to reduce inflammation and pain (both from Bioforce, 01294 277344). Glucosamine hydrochloride provides nutrients to rebuild cartilage and ligament, while MSM, a form of sulphur and collagen, can also be taken for connective tissues (both from Higher Nature, highernature.co.uk). Limit sugar, salt, dairy, fried and processed food - they exacerbate joint problems.

My three-year-old has had molluscum contagiosum on her face for 18 months. She caught it from her elder brother, who had it for nearly three years. Our GP says to wait until they fade, but they are spreading, and I am worried for my middle child, who has no sign of them.

Molluscum contagiosum is a viral infection of the skin, producing pink, wart-like spots, the centres of which are concave. Children with chronic molluscum often have other symptoms and may get flare-ups when under stress, or when the immune system is low or already stretched due to food intolerances. Homeopathic treatment is effective because it addresses all symptoms and improves health holistically (Society of Homeopaths, 01604 817890, homeopathy-soh.org). I find that Tisserand Antiseptic Cream (tisserand.com), applied topically, accelerates healing and prevents spreading . Deactivate the 'mother' wart with this cream. Wart 'folk' remedies such as covering it with banana skin, garlic, duct tape or even nail varnish, will weaken the rest. Boost your children's immunity with echinacea (Echinacea Junior, one tablet twice a day; from Bioforce, 01294 277344); and with Sambucol (anti-viral formula with propolis), zinc (Sublingual Zinc, an eighth of a scoop daily for two months), a multivitamin and mineral (Dinochews) and vitamin C (calcium ascorbate, a quarter-teaspoon daily; all from Higher Nature, highernature.co.uk). With this, you may find that your middle child doesn't become susceptible to the virus.
