It is very important that the silicon base is included -- however,
the herb horsetail is in the formula, and it is a good source.

Silica deficiency in humans has not been extensively studied. It is
known that silica is essential to good health and a youthful
appearance, and that the mineral becomes more important to our bodies
as the years progress. If you suspect that you may not be getting
sufficient amounts of this trace mineral in your diet, you may want
to consider supplementation.

Nevertheless, you need not look far to find (other) natural sources
of silica, since Noble recommends that, "If a person has symptoms of
silicon deficiency, such as very dry hair, of silica, including
horsetail or oat-straw, or food sources, such as wheat bran,
soybeans, beets, leafy vegetables and brown rice." However, keep in
mind that the less adulterated the secondary source of silica is, the
more benefits it will have to offer. So, strive to find organic,
unprocessed sources of these products. Silica supplements containing
standardized orthosilicic acid are also available, some fortified
with silica partners such as magnesium, potassium and calcium.

I also noted from another website that garlic and onions, both raw
and cooked, are sources.

silicon dioxide can also be applied directly to the swollen (ankle(s)-
and some people inject it IN! -"Cheyenne Cin"- P.S. Perhaps the herb
horsetail is quite beneficial against water retention, edema.

I know that when the swelling or vein damage is in the legs or feet,
ankles, that horse chestnut is also very essential. But for serious
ankle swelling or water retention, esp. if the cause originates with
a bug bite, tea tree oil (and DMSO), and clay powder mixed with apple
cider vinegar, to draw out the toxins, are also excellent. The
potential for either a virus or blood clot reaching the brain is the
biggest danger, so the edema (water) needs to be taken care of at
it's location. Pregnant women or women in monthly cycles also retain
water, as so women who sit a lot or who are taking certan
prescription drugs. (Or men who are) If in ankles, etc., keep leg(s)
elevated as much as possible. And exercise more if it's not from a
bug bite or a drug- sedentary (leg) lifestyle is the culprit.
