Another meta-analysis showed that Berlin. Their inspiration came from the neuroscientist autogenic training is effective, but less than meditation in Dr. Oskar Vogt, who found that it was possible to reach a reducing anxiety over ten years [4]. Hence, it seems to be an hypnotic state without relying on external suggestions but appropriate tool for many psychosomatic disorders, though purely on the self. not more than unguided techniques such as meditation. Schultz aimed to develop a method that rendered the patient responsible and independent of the hypnotist. Hence the name autos (self) and genos (creation). The underlying principle is based on ‘selective awareness’ through autosuggestion in order to reach a higher level of self-regulation and relaxation. Such selective awareness is reached by focusing on self-suggestions and internal physiological processes, e.g. the regulation of blood flow to specific body parts and instructing these parts to become warm and heavy. While applying this technique, emotional responses and physical sensations can be triggered and released. This sort of self-regulatory training is most effective when the individual is highly motivated and receptive to instructions and suggestions. Furthermore, the individual must maintain a strong sense of concentration and body awareness, meaning that the technique may not be suitable for all. Still, autogenic training – apart from sharpening Source: http://www.entspannungs-kurs.de/autogenes-training.php one’s focus and mind control – is used for a broad variety of conditions, such as insomnia, hypertension, tension headaches, migraines, bronchial asthma, and for certain References types of pain disorders [1,2].

He suffered from the rare condition lambda light-chain amyloidosis. Whilst the common therapeutic approach was rather ineffective, daily consumption of 1.5 to 2 liters of green tea per day reduced his symptoms substantially [7]. Meta-analyses of studies investigating the effects of daily green tea consumption reveal that there are major variations in the daily intake, concentration, and preparation methods of green tea, and have not found definite proof of clinically relevant benefits [1].
