What is Oxalic Acid?

Let's begin by defining this term. It is a colorless, crystalline organic compound which can be found in many plants, including those that we often serve at our family table.

It is often used in manufacturing in purifying agents such as bleach; it also contains rust removing properties and is sold as such. It also combats some parasites such as particular mite species, and it works well to create a shine on certain surfaces, such as marble.

It is also used in the pharmaceutical industry.

Toxicity, Signs, Side Effects, Symptoms

Oxalic Acid is a poisonous substance that can be lethal in certain amounts. The lowest published lethal oral dose that we were able to identify was at 600 mg/kg of body weight. To put things in perspective, it would take about 24 ounces of raw parsley to reach this amount.

Side effects of toxicity include the following symptoms:

joint pain

indigestion

kidney dysfunction issues, including kidney failure
