Cassava flour, also known as Thai raw flour. This is the name of a starch, which is extracted from the tuberous roots of tropical plants. This plant belongs to Acer and belongs to the same family as castor, rubber and jatropha curcas. Boiled with water and heated, it will be transparent and elastic in taste.

Cassava powder is generally used for external use, mainly for swelling and pain, traumatic injury and so on. But even for external use, it needs the guidance of Chinese medicine, because cassava is really poisonous. If heating can eliminate some toxins, it is hard to say whether the toxins can be completely eliminated or not. If you eat cassava by mistake, it will be mild nausea and vomiting, severe limb convulsions, and even death due to respiratory failure.
