How to Take Note of Cashew Poison? 

In many online health forums, the most frequently asked question is “Are Cashews Poisonous?” or “Are Raw cashews poisonous


Raw cashews contain urushi- the same toxic chemical that is found in poison oak or ivy. Cashew poisoning is rare, but if urushi is ingested at high level, it can be deadly. So, when you visit the store to buy “raw cashews”, check that these nuts are not entirely raw and have actually been steamed. To remove urushi, a rigorous steaming process is ensured. However, before this process, cashews are green!

During the roasting process, parts of the cashew are handled with much care because it is related to poison ivy that can cause an allergic reaction in people sensitive to the chemical.

Roasting (at high temperatures) the de-shelled cashews destroys toxic oils, which is why commercially prepared cashews are safe for your health. Therefore, make sure that you buy roasted cashews from the grocery store. Also, you need to add plenty of grains, fish, eggs, fruits, and vegetables, in your daily diet so don’t let cashews dominate your diet.
