I’m finding it difficult to shake off a persistent sniffle and I’ve noticed my energy levels have started to dip. I’m in my 40s and make sure to eat well and take plenty of exercise. What would you recommend?

Echinacea is a great natural remedy when it comes to bolstering the immune system, and will also help to fight off an existing infection. The root, naturally rich in alkylamides, is anti-inflammatory and is likely beneficial in the acute stages of a cold or flu. It may also be more effective when used in conjunction with other immune-supportive herbs such as black elderberry, ginger root, medicinal mushrooms, and andrographis.

The aerial parts of echinacea are thought to enhance the immune system and are suitable to be taken in a lower dose over a longer period.

Most remedies are made using either Echinacea purpurea or Echinacea angustifolia. Clinical research shows that Echinacea purpurea has the highest level of immuno-modulating activity, which makes it the most suitable choice for anybody with auto-immune concerns.

A.Vogel has a range of six different echinacea products — all of which use organic Echinacea purpurea, extracted using alcohol and water. Its Echinaforce is licensed for the symptomatic relief of colds, influenza-type infections and similar upper respiratory tract infections. The company also makes uniquely formulated tincture tablets. Available from most health stores and pharmacies, you can order the A.Vogel range online at .

Taking an immune supportive remedy should go a long way towards improving your energy levels. If you find yourself needing additional support, then you might like to consider supplementing with Coenzyme Q-10 (CoQ10). CoQ10 is a crucial component of mitochondrial function, helping to convert the energy from fats and sugars into cellular energy.

Finally, make sure you include zinc-rich foods in your diet, such as nuts, beans, dairy products, chickpeas, fruit, eggs, wholegrain cereals, pumpkin seeds, potatoes, figs, yeast, tahini, and most meats. Zinc is particularly useful in addressing sniffles, sore throats, and respiratory infection as it is secreted by the body into fluids to act as an antiseptic.

I suffer from vertigo, which seems to come and go. What natural remedy would you suggest?

It can stem from a number of underlying conditions, including middle ear infection, labyrinthitis, Meniere’s disease, epilepsy, toxaemia, brain disease, or it can appear as a result of unknown causes. Vertigo can also be triggered by a number of drugs, including antibiotics, caffeine, alcohol, blood-pressure medication, and sedatives; with one of the most common causes being aspirin.

One of the most common issues in people who develop vertigo is dehydration. A simple place to start in treating your condition is to improve your hydration levels by adding a tiny pinch of sea salt or a squeeze of citrus juice to your water to help maximise absorption. Another common issue found in more than 80% of all people who suffer from vertigo is either high cholesterol or high blood sugar levels. While this is easily addressed through dietary changes, it is also worth considering supplementation with a high-potency vitamin B-complex to improve the health of the central nervous system, increase blood flow to the brain, along with lowering cholesterol levels.
