Nature Cures natural health advice


Let food be your medicine










Also known as CF or mucoviscidosis, cystic fibrosis is an inherited disease of the glands, including mucus and sweat glands. It mostly affects the lungs, pancreas, liver, intestines, sinuses and sex organs but it doesn't affect the brain. There are around 9,000 people with cystic fibrosis in the UK although around one in 25 people carries the faulty gene which causes the condition.

In cystic fibrosis sufferers, the mucus becomes thick and sticky and builds up in the lungs blocking the airways. This leads to repeated, serious lung infections that can damage the lungs. Lung function often starts to decline in early childhood in people and, over time, cause permanent damage to the lungs and severe breathing problems. The thick, sticky mucus can also block tubes, or ducts, in the pancreas. As a result, the digestive enzymes that the pancreas makes can't reach the small intestine. Without these enzymes, the body can't absorb fats and proteins. This can cause vitamin deficiency and malnutrition.

Cystic fibrosis also causes the sweat to become very salty. As a result, the body loses large amounts of salt during perspiration. This can upset the balance of minerals and cause a number of health problems. Examples include dehydration, increased heart rate, tiredness, weakness, decreased blood pressure, heat stroke and, rarely, death.

A defect in the CFTR gene causes cystic fibrosis. This gene makes a protein that controls the movement of salt and water in and out of the body's cells. Every person inherits two CFTR genes; one from each parent. Children who inherit a faulty gene from both parents will have cystic fibrosis. Children who inherit one faulty gene and one normal gene will be "cystic fibrosis carriers". Carriers usually have no symptoms but they can pass the faulty gene on to their children.

Around 3-10% of cystic fibrosis sufferers become infected by the mycobacterium abscessus bacteria, (which is distantly related to the bacteria that causes tuberculosis) It is not known why it is more likely to infect people with cystic fibrosis but it could be related to problems with the immune system.

It was thought that this bacteria could only be caught from water and soil but has now been discovered to be able to infect person to person. It is believed that it becomes aerosolised when people cough and because this bacteria is tough it hangs around in the air. It causes lung damage and can be incredibly hard to treat with infected patients needing months of treatment with toxic drugs.


Betulinic acid is a tumour fighting, antifungal, anti inflammatory and antibacterial compound found in the bark of white birch trees, chaga mushrooms and winged beans which can treat mycobacterium abscessus bacteria infections.

Consume plenty of citrus fruits and pineapple juice.

Add unrefined sea salt, spices and herbs to meals and drink bottled mineral water.

Green vegetables and plenty of fibre daily will help to readdress any intestinal bacteria imbalance and boost the immune system.
