Herbal medicine is a discipline that uses medicinal plants in their various forms to healthy purposes. It is certainly the oldest of all the medicines, because the man uses plants for health benefits since he appeared on Earth. The use of plants and natural remedies is still the only tool used by primitive peoples still or otherwise unable to enter the pharmaceutical drugs.
Of all the natural medicines is that which comes closest to conventional medicine, as it acts on the basis of active ingredients with well defined activities on the body. However, it differs because, unlike it, believes that the auction be traced back to the plant in all of its constituents, rather than the single action of active purified and isolated.
The extraction of active ingredients from plants may be carried out in various ways, the best known of which is infused. This is the classic tea. The plant is placed in contact with boiling water. The active extracts that are treated better by the body. The Chinese used preferably in the draft, the methodology by which the plant is put in contact with the water boil.
There are many natural remedies offered by nature for the treatment of anxiety and stress, including the most commonly used and is known as valerian, passionflower, hawthorn and Hypercom. In the composition of natural products for anxiety and stress also chamomile, lemon balm, linden. The real effectiveness of these remedies is not scientifically proven, but that does not mean they have no effect. They can even be a good alternative to drug therapy in mild cases or may be associated with these, also in a gradual replacement of the drugs, given the lower incidence of side effects.
In particular, the hawthorn seems to have an effective action in combating the anxiety due to the mild sedative sull'eccitabilità nervous system and heart rate. It is believed that it is able to dampen the feeling of anxiety, dizziness and insomnia.
Hypercom in turn has antidepressant and sedative action due to inhibition of certain neurotransmitters in the central nervous system and increased nocturnal secretion of melatonin, which regulates the sleep/wake.
Passion fruit is attributed to the depressive action on the autonomic nervous system (intestinal motility, heart rate, etc.) and an anxiolytic effect similar to that produced by benzodiazepines; it is therefore particularly useful in the forms of anxiety already being treated with psychotropic drugs.
These activities would be attributable to the strengthening of particular mechanisms of nerve transmission, by increasing the availability of the neurotransmitter gamma-amino-acid butyric acid (GABA), which affects the central nervous system depressant, although some studies have shown the mechanism of action could be much more complex and involve other neuronal systems.
