I've already mentioned that Candida can already commonly produce dangerous toxins such as poisonous aldehydes, arabinose sugars and alcohols.
Dr Shaw now also reports heavy oxalate production from candida and particularly from the Aspergillus forms of fungus and mold. He also reports that that these insoluble oxalates can form anywhere in the human body, not just in the kidneys and gallbladder as stones but also in the skin, bone (causing anemia), joints, vulva (causing pain), blood vessels, lungs and even the brain (a major factor in autism). Oxalates can also combine with mercury and lead in the body which makes it much more difficult to get rid of these heavy metals. Oxalates can also combine with useful nutrients like calcium, magnesium, zinc and other important body minerals -- thus making them insoluble and neutralizing their beneficial effects in the human body.
Oxalate crystals tend to be large and sharp so any mechanical pressure such as occurs in the bladder or any tissue containing oxalates can also cause considerable pain. This is also why Dr Shaw believes that oxalates play such an important causative role in myalgias -- eg fibromyalgia.
If you have an oxalate problem in your body, both Dr Shaw and Susan Owen recommend taking both magnesium citrate and calcium citrate at mealtimes to prevent oxalate crystal formation and to prevent oxalic acid absorbtion into the body respectively. Vitamin B6 should also be supplemented at higher dose because this vitamin is used to make an enzyme called alanine-glyoxolate amino transferase -- an important human enzyme that actively dissolves and removes oxalates safely from the human body.
For a more in depth view on all the chronic problems caused by oxalates see the following articles:
Oxalates and Autism -- Susan Owen
The Role of Oxalates in Autism and Chronic Disorders -- Dr William Shaw
As an aside, I also think that taking daily amounts of Chanca piedra would be highly beneficial for oxalate problems in the body, since CP is already well known to dissolve and safely remove oxalate stones from the gallbladder and kidneys.
