Understanding depression

Feelings associated with anxiety include impatience, apprehensiveness, irritability, and decreased ability to concentrate. People suffering from anxiety may also worry, for no particular reason, that something bad is going to happen to themselves or their loved ones. Individuals with anxiety disorders may make such statements as: - I always thought I was just a worrier, but I would worry about things for days, to the point where I couldn't even sleep. - I had a very strong feeling of impending doom, like I was losing control in an extreme way. - I was always worried that if I didn't do certain things, my parents were going to die. - I felt as if my heart was going to explode, and I couldn't calm down.

Experts have yet to agree on the root cause of anxiety disorders. In fact, most concede that several factors may be at work in each case.

In addition, with new findings about neurogenesis (birth of new brain cells) throughout life, perhaps a method will be found to stimulate growth of new neurons in the hippocampus in people with post-traumatic stress disorder.

Medication is most helpful when there is clear disorder or, sometimes, a specific target symptom for a particular drug. Usually, a pattern of symptoms point to a specific chemical imbalance. Whenever an imbalance appears evident through a person's disordered behavior and emotional state, medication centers on modifying the strength of the signal or readjusting the balance among them.

Hoodia herbal pills helps weight loss

Independent tests conducted in Leicester, England on obese individuals from all walks of life have proved that over a 15-day period, food intake was reduced by 1000 calories a day.

Laboratory experiments show animals automatically restrict their food intake when taking hoodia orally. Rats, a species that will eat anything from meat and plants to indigestible fiber, lowered their dietary calorie intake to a degree that made them get thin when fed comparative amounts of hoodia.

The pure Hoodia that contains appetite suppressant qualities is only grown in one specific region in South Africa. If the Hoodia is from China, USA or any other part of the world and is not accompanied by a South African Government Certificate of Authenticity, the product is inferior and ineffective.

All this means that if hoodia really catches on with the public -- the supply will be even tighter for many years. Prices are going to go up, and eventually, only the wealthy may be able to afford the pills necessary to lose weight.

Hoodia is registered as a protected species to prevent Bio-Piracy but is allowed to be grown on a handful of commercial farms in South Africa owned by private farmers.

The Hoodia Gordonii plant originated in the southwestern part of Africa and grows best in the semi-arid areas of South Africa primarily the Kalahari. In its native habitat it is extremely difficulty to identify because it looks similar to succulents of the same family of which there are many. Only an experienced botanist or as the case in South Africa with Hoodia Gordonii a San people can identify the plant prior to it's blooming.

Preventing serious drug interactions

The Internet has changed the way we live, work and shop. The growth of the Internet has made it possible to compare prices and buy products without ever leaving home. But when it comes to buying medicine online, it is important to be very careful. Some websites sell medicine that may not be safe to use and could put your health at risk.

When a drug is taken orally, it usually travels from the stomach to the liver, where it can be metabolized-the process of breaking down and removing chemicals from the body. Enzymes are complex proteins that act as catalysts in starting or speeding up chemical reactions. They cause a specific chemical change in other substances without being changed themselves.

Three phases of clinical trials in humans must happen before a drug can be marketed. Phase 1 studies focus on a drug's side effects and how the drug is metabolized and eliminated from the body. Phase 2 studies focus on a drug's effectiveness. And Phase 3 studies gather more information on safety and effectiveness, which includes using the drug in combination with other drugs.
