Insulin, for diabetes
What is it? The body obtains most of its energy from glucose, a simple form of sugar produced by the intestine from the breakdown of starch and other sugars. Insulin is a hormone manufactured by the pancreas gland which enables body tissues to use glucose.
What is it good for? Insulin is given to supplement or replace natural insulin in the treatment of diabetes mellitus. It is used to treat juvenille insulin-dependent diabetes (type 1) and may be used in some people with adult maturity-onset diabetes (type 2).
How does it work? It works by promoting the uptake of glucose in body tissues and helps prevent an excessive rise in the level of glucose in the blood. It is available in a wide range of injectable forms which are either long-acting, short-acting or intermediate.
Any contraindications? Oral antidiabetic drugs and monoamine oxidase inhibitors (a type of anti-depressant) taken with insulin can increase the risk of low blood-sugar. Corticosteroids and diuretics can oppose the effect of insulin and betablockers can mask the warning signs of low blood sugar.
Possible side-effects? Dizziness, sweating, weakness and confusion usually indicate a low blood-sugar level and it is necessary to eat or drink something sugary to alleviate these symptoms. If a fit or loss of consciousness occurs, immediate medical assistance is required. Allergic reactions such as rash, swelling and shortness of breath can occur but are rare.

Alternative Remedy: Oats, for stress
What is it? Oats are a type of cereal, most conveniently eaten as oatmeal but can also be taken as a fluid extract. Shredded straw can also be boiled for use in a bath.
What is it good for? Considered one of the best remedies for stress, nervousness and exhaustion, they are also valued for use in treating neuralgia and irritated skin. Oats are very nutritious containing protein, polyunsaturated fats, B-complex vitamins, calcium, potassium and magnesium. Research shows that patients given a daily dose of oats lowered their cholesterol levels.
How does it work? Their nutritional constitiuents make it an excellent tonic for the nervous system. High levels of silicic acid in straw make it a valuable skin conditioner.
Any contraindications? Oats are not suitable for coeliacs, i.e. those who show an intolerance to gluten.
Possible side-effects? Oats should always be cooked or pre-soaked otherwise the phytates present will prevent absorption of minerals such as calcium and magnesium.
