Silica and quartz are crystalline compounds, known carcinogens, which cause cancer. These carcinogens are within the clay and the clay dust. People who are using these products must wear respirators, not dust masks, because the breathing of this dust is so harmful and can cause silicosis (cancer of the lungs). P.O.L. Sorb? contains no silica or quartz and has no known health risks other than dust. Prolonged exposure in excess of the permissible exposure limits of any dust is not good. With P.O.

No. None of the five varieties of Healthy Pet? Cat Litter contain silica dust that has been known to harm a cats' respiratory system. See similar questions...

FIJI Water is an artesian water which makes it distinct from other waters. FIJI Water's mineral composition and taste are the result of its source: an artesian aquifer on the islands of Fiji. The volcanic rock on the island acts as a natural filter for the water. FIJI Water filters through layers of this mineral-rich volcanic rock over hundreds of years gathering minerals like silica. The unique blend of these minerals is what leads to the distinct soft, smooth taste of FIJI Water. See similar questions...

When speaking about digestive enzyme formulas, no. As active protein molecules, the enzymes do not accumulate in the body. They impart enzymatic activity that lasts anywhere from one to four hours and then they are eliminated from the body or the proteins are broken down and the amino acids are used for other purposes. As with any herbal or nutritional supplement, evaluation of amounts and over consumption should be determined on an individual basis. [back to top] See similar questions...

External sources of alkali from soil, deicers and industrial processes can also contribute to reactivity. See similar questions...

Silica fume is a by-product resulting from the reduction of high purity quartz with coal in an electric arc furnace in the manufacture of ferro silicon and silicon metal. Silica fume, which has a high content of amorphous (uncrystallized) silicon dioxide and consists of very fine spherical particles, is collected by filtering gases escaping from the electric arc furnaces.

Under normal conditions, there are no harmful effects from electrology treatment. Most undesirable aftereffects are caused by the patient. Scratching, picking, or using heavy makeup, and of course general uncleanliness, can cause problems. Caution should be taken with diabetics and patients prone to keloids. To avoid harming the patient, the electrologist should not treat areas inside the nose or ears, or wherever there are skin irritations, until the patient has been examined by a physician.

Abscesses at the site of BCG injection are frequently reported. It is often assumed that this is due to bad technique, as the injection should be given intra-cutaneaously and an accidental intramuscular injection may result. Proximal lymph node swelling and abscess formation may rarely occur. If the injection is given at the correct site, over insertion of Deltoid in the upper arm, the swelling will develop in the axillary lymph nodes. See similar questions...
