Porphyrin is known as the "longevity vegetable". Its protein content is equivalent to that of soybeans, and it is also rich in vitamins and other nutrients. Its nutrients are easily digested and absorbed, making it very suitable for elderly people with reduced digestive function.

It should be noted that it is best to consume 15 grams of seaweed each time. It is best to soak your hair in clean water before eating and change the water once or twice to remove contaminants.

Porphyry is cold in nature, so those with spleen and stomach deficiency, poor gastrointestinal digestion, or abdominal pain and loose stools should eat less.
