Great Topic! Various authors have associated iris pigments with heavy metal, various drugs or inorganic settlements in the body, inherited and acquired that include: Mercury or Hydrargyrum - Quicksilver In a blue eye, Mercury shows up as a whitish or silvery gray circular line of a metallic lustre in the circulatory area of the brain region. The brown eye will display a more blue or greenish tint. Lead or Plumbum This drug may be seen in the iris as a lead blue, or bluish gray circular discoloration in the stomach - intestines region. Although this drug has an affinity for the intestines, other organ areas may also have settlements in severe cases. Iodine No other drug shows up shows up more clearly than iodine although signs will differ according to internal or external absorption. Internal absorption will show up as a bright red, reddish brown, or orange colored spots that sometimes have a white border showing irritation and inflammation, or process of elimination. External absorption shows up as an orange or pinkish hue, and appears in the form of streaks or clouds. This drug sign can show up in any area of the iris, although more frequently in the liver, kidneys, gastro-intestinal, lungs, pancreas, and brain areas. Iodine pigmentation is always a brighter red and more diffuse than psora. Psora or Itch Spots Psora may be seen as dark or muddy brown spots that can range in various sizes, and can be found anywhere in the iris. These spots will appear after the suppression of itchy eruptions or parasites. It has also been noted that these spots may be indicative tubercular or malignant tendencies. Quinine Depending on certain chemical combinations associated, Quinine shows as a yellowish, cloudy discoloration or sometimes greenish cloudy hue. Quinine has an affinity to settle in the brain areas, eyes, ears, and digestive systems. Bromides Bromides show in the outer-most iris area closest to the sclera as a whitish or yellowish white crescent with the affinity to settle in the brain and nervous system areas. Bromides are used heavily in the pharmaceutical Industries. Arsenic Early stages of arsenic pigmentation will show as a grayish-white veil like specks over the gastro-intestinal or respiratory areas. Later stages shows up as grayish white flakes and may appear singly or irregular groups in the circulatory area. Phosporus Phosporus can show up as whitish, grayish, and faded yellow specks and clouds in the gastro-intestinal, brain, limbs, diaphragm, and heart areas. May appear a lighter amber color in brown eyes. Aluminum May show up as blue-gray spots in the circulatory area. Sodium Sodium will show up as a slight metallic lustre in the circulatory or lymphatic areas. This ring may fully surround the iris or may be found in parts depending on the quantities of inorganic salt not eliminated in certain circulatory areas. Sulphur Sulpher shows up in the gastro-intestinal area producing a yellow or dark brown, sulphur like color. When the sulphur sign is seen in the iris, irregular conditions in the autonomic nerve wreath may be seen indicating a sluggish condition in the intestinal tract. Creosote Creosote produces a fine grayish or ashen gray veil over the whole iris. Long term cases will show up as sparkling white spots in the stomach or intestinal areas. Strychnine Strychnine shows in the iris as a white wheel-like circle in proportion around the pupil in the stomach area. close inspection may find lines or spokes radiating from the pupil. Ergot Ergot shows as a series of bright red, sometimes rust-brown spots in the gastro-intestinal tract and may sometimes be found as bright red spots throughout various organs in the iris. It is also seen at times as a red or rust-brown circle in the stomach area. Glycerine Glycerine shows as large white spots or clouds in the skin, kidneys, and lung areas. Salicylic Acid Salicylic Acid shows as a whitish gray cloud or veil spreading unevenly over the outer margin of the iris, being more pronounced in the upper part. It is frequently associated with he sodium ring. This drug also has an affinity to the gastro-intestinal tract. Ferrum or Iron Ferrum & iron will show up as a rusty-brown discoloration of the entire gastro-intestinal tract. Bismuth Bismuth ingestion will show as dark-gray irregular circles in the digestive tract. Vaccine Virus Vaccine Virus shows as a distinctly superficial black or muddy brown spot. This spot is always surrounded by white indicating that the virus is causing irritation, creating an inflammatory area around it. Vaccine virus has the Tendency to darken the entire iris and may also cause white lines to appear in the liver, spleen, and bladder areas for reason of elimination. Opium Opium is seen in the iris as pure white straight lines radiating from the pupil or the autonomic nerve wreath outward. This is most noticed in the upper part of the iris. Morphine Morphine is similar to opium although appears in the iris as finer white lines which are very superficial. Cocaine Cocaine is similar to that of morphine as it appears in the iris. Nicotine Nicotine is similar in appearance to that of the vaccine virus in portraying the dark, smokey effect. In heavy smokers, it is common to find a number of nerve rings and some abnormalities in the autonomic nerve wreath (collarette). However, I think that many of the above iris pigment sign signs could be caused by other systemic anomalies which could also make good forum discussion! Pupil analysis would also very valuable in diagnosing heavy metal toxicity including the inner pupillary border (IPB) which is said to show signs of vaccine damage. Another good forum?!? ;) Profbryan
