章節 1514: Chapter 1514-going south and going north

Oregonian sorrel was quite common in the redwood forest on the West Coast of the United States. It was a unique plant that grew here, and its flowering period lasted from spring to early autumn. If a traveler was trapped in the forest and faced a food shortage crisis, it was the right choice to use this plant to fill their stomachs to survive the danger. According to its classification, this plant was indeed an edible plant. It could be eaten from its leaves to its roots.

However, The Oregonian sorrel contained a large amount of silicate. Humans could barely eat it, but they couldn't eat too much. If they wanted to eat it, they had to try to eat the leaves and drink it with water. Otherwise, it would lead to silicate poisoning, not to mention the parrots, who had a low tolerance for silicate.
