Parkinson's is a progressive paralytic condition that affects predominantly but not exclusively elderly people. According to the Merck Manual, it affects 1 in every 250 people over 40 years old and 1 in every 100 people over 65 years old.

Multiple Sclerosis is a serious neurological condition that affects the myelin sheath that surrounds the nerve fibers, leading to progressive neurological problems involving either parts of or the whole body. Symptoms can come on at any time of life and can often begin suddenly.

Allergies is the generic term given to when a person has an "allergic" reaction to some kind of environmental or other factor they have come across. When the body has an allergic reaction, it is producing too much histamine, it is overreacting whatever it has come across.

Arthritis is an inflammatory condition of the joints. There are two main types of arthritis seen, osteoarthritis and rheumatoid arthritis. The former is often called a wear and tear arthritis as it most often affects elderly people or those who have overused certain joints and is often see in the large joints such as the hip.

Herpes is a very common condition, caused by one of more forms of the herpes virus. There are a number of viruses known to cause herpes, the most common ones known as Herpes 1 and Herpes 2. The first one creates the "coldsore" around the mouth, whilst the second type characteristically produces eruptions in the genital region, although other areas can be affected.

It is commonly thought that one can never get rid of the virus, that once there it is destined to stay, with periodic eruptions. Often with herpetic eruptions, especially type 2, the eruptions do return quite regularly, often exacerbated by stress. However, even if the virus does lie dormant in the body when it is not erupting, there is no reason why these eruptions have to come back. Given that we know that the body can cure itself, then it makes sense to consider that the body can maintain a higher level of health. Herpes outbreaks are often an indicator of the level of energy in the body and so if this energy can be optimized, then the tendency for eruptions can disappear. Therefore, in homeopathy, herpes can be effectively treated. As with all chronic conditions, this means treating the whole person, finding the correct remedy to stimulate the optimal health in each person.
