Oxalic acid is the chemical compound. This colourless solid is a relatively strong carboxylic acid, being about 3,000 times stronger than acetic acid. The dianion, known as oxalate, is a reducing agent as well as a ligand for metal cations. Many metal ions form insoluble precipitates with oxalate, a prominent example being calcium oxalate, the primary constituent of the most common kind of kidney stones. Typically oxalic acid is obtained as the dihydrate.
Oxalic acid is toxic to humans, with LD50 which means 50% leathal dose of 71 mg/kg. It has an extremely irritating taste. Prolonged handling of aqueous solutions cause joint pains. Humans excrete several milligrams in urine
Goitrogens are substances that suppress the function of the thyroid gland
well a little research i found out wat i was looking for go figure but i thought i share obivously these are the pure form and are found in a lot of plants :
cassava Soybeans Pine nuts Peanuts Millet Strawberries Pears Peaches Spinach Bamboo shoots Sweet Potatoes but cooking inactives the goitrogens but not the oxalic acids and arent life threating as they require a 50% level is required to kill a human. as reading thought these i see why there not good as a base feeder even if you where to use another gut load as brain function is suppresed and can cause sore joints so this is some quite disturbing info and realize the amount my cham has ingested wont cause any harm but knowing that it could with prolong expose and enough of it just isnt good
