They travel to the breast where they deliver instruction to initiate mammogenesis and for that reason are used in herbal preparations for natural breast enhancement or natural breast enlargement. Which plants are used to produce the various basic chemical substances that make up all major drugs? And just how do these chemicals affect the body? The prevailing scientific opinion is favourable as there is substantial research indicating that phytoestrogen holds great potential for benefits. Recent epidemiological studies have suggested that typical Asian diets with herbs such as fenugreek and fennel appear to be associated with a significantly lower risk of breast, prostate and colon cancer as well as a reduced incidence of heart disease. The amount in plants varies with genetic differences between plant varieties or the species; influence of environmental factors during growth; and differences in harvesting or the subsequent processing. Treatment - why does the human brain respond to plants of power?
Isoflavones are found almost exclusively in legumes, the soya bean being the most abundant source. The two most important soya isoflavones at present are genistein and daidzein. But lignans are also a very important source of these subsances in the British diet as they are present in most fibre providing foods. Ascertained levels of herbal sources of lignans and isoflavones are currently being researched.
These diseases have long been associated with Western diets and therefore the studies reinforce this idea. Hormones are chemical substances produced by the body's endocrine glands and released into the bloodstream to act as messengers, travelling through the body with instructions to trigger activity in their target tissues. These tissues each contain receptor sites specific to a certain hormone and the effect is initiated when the hormone docks at those receptor sites. Estrogens are released from the ovaries to trigger breast enlargement.
Highest amounts of the phytoestrogens occur in soya products, alfalfa, linseed, fenugreek, fennel and red clover, soya being a major potential source of human exposure. A limitation on their hormone balancing actions is they do not have estrogenic properties when inside the herb or even at the time they are consumed, but in fact aquire them only during the digestive process through the actions of bacteria residing in gastrointestinal tract. This means that the biologically useful forms, the metabolites, are dependent for their existence upon the digestive system being in good order and adequate microflora capable of converting plant compounds into active forms.
Inappropriate diets, stress, and anti-biotics can cause significant disruption to the ideal healthy balance of the gastrointestinal organisms. And high fat intake is another culprit. One thing that has a positive effect though is fibre. Antibiotics can very quickly destroy friendly bacteria as well as the invaders they are meant to exterminate.
