I have some kidney issues and slightly reduced kidney function which is made worse from parasite infection. I started to take Diatomaceous earth today 1tsp x 2 so far and I have noticed that my kidney pain is noticeably worse. I was hunting around on the net and some sites say that silica can help kidneys but also came across some articles that suggested the too much silica can cause irreversible kidney damage (See last sentence of paragraph in article below)
Horsetail is generally considered safe. Horsetail will promote urination, adequate fluid should be consumed when taking horsetail preparations orally. People with heart or kidney disorders should not use horsetail. Women who are pregnant or breastfeeding should not take horsetail. Horsetail is contraindicated in those who have edema because of an impaired heart or kidney function. Horsetail is known to block the absorption of thiamine, and lead to thiamine deficiency.
This is only true of fresh horsetail grass (shavegrass). The fresh herb contains the enzyme thiaminase, which is why it can reduce thiamine levels. But the enzyme is destroyed upon drying or cooking.
Long-term use or high doses of horsetail have caused irreversible kidney damage due to too much silica.
This is untrue. I do agree with their statement to avoid the herb in cases of kidney disease or heart disease. I also recommend avoiding it in cases of Raynaud's disease or phenomena as well as diabetes. This is why you never see me recommending this herb since it is impossible to screen everyone who may use the herb. But the problem is not with the silica in horsetail. In fact bamboo is 7 times higher in silica than horsetail grass, but I recommend this because it is a much safer silica source. The problem with horsetail grass is that it contains nicotine, which constricts the blood vessels. This can lead to problems in people with already impaired blood perfusion such as diabetics, or those with kidney disease, Raynaud's or heart disease. Bamboo on the other hand actually dilates the blood vessels increasing circulation. So it does not pose the dangers of horsetail grass.
Can you please give me your input on this. Thanks very much
EDIT - tried some parsley tea and the pain is worse again, now all over my back - a little bit concerned.
This really sounds like an issue of calcium oxalate stones. You should avoid oxalate sources which include parsley. Here is a link with foods containing oxalates:
Some herbs are also high in oxalates such as rhubarb root, sorrel, yellow dock, purslane and cat's claw.
Excess vitamin C in the body also breaks down in to oxalic acid. So do not take high levels of vitamin C.
