Bracken or Pteridium aquilinum are easy to find around the world. This type of ferns contain a carcinogen called ptaquiloside.
Ptaquiloside can cause DNA damage to cancer in the digestive system. It can be poisonous only if the ferns aren't cooked until it's fully cooked.
According to 2001's published research at the International Journal of Cancer, raw Bracken also contains a thiaminase enzyme. This enzyme can break down vitamin B1 and cause a cervical disease.
- Royal Pakis (Osmunda regalis)
General called royal fern or flower ferns, Osmunda regalis are many found in Asia, Africa, and Europe. It usually grows on the banks of rivers and swamps.
Its roots are used as the media planting orchids. The young trunk is used to be consumed and called has a taste similar to asparagus.

So far, there's been no cases of poisoning from recorded vegetable ferns.
How to Cure Sale Pakis Not Poisoned
- Bracken.
According to the official US Forest Service website, Bracken contains a pretty high ptaquiloside. However, the ptaquiloside itself is dissolved in water and damaged by the heat and the alkali conditions. The concentration of ptaquiloside on the Bracken ferns goes down if it's placed at room temperature and it's barely cleared when it's cooked to the boiling point.
The best way to process this fern is to soak it and cook it with fire. If you want to incorporate it into a salad, you can also replicate how to process Bracken from Japanese and Korean. Soak in a solution of water and chalk to remove the poison.
Although relatively safe to consume, Bracken ferns should be eaten in small amounts and not too often. The goal is to avoid the risk of cancer that can't be lost by a hundred percent.
