It was edible in the past, but now the environmental pollution is serious, so it is not recommended to eat it. It may have an impact on the body.

reed bud is the tender bud of reed, which we call reed bud for short. The newly-grown reed bud looks very similar to bamboo shoots. The outer layer of reed bud is turquoise, and the outer layer is pushed aside, and the inside is similar to bamboo shoots. Generally, reed buds are relatively fresh in spring, and the longest picking time is only about half a month. And reed buds grow in the water. If the water is deep, they may still be at the bottom of the water, which is very difficult to pick, so we rarely see reed buds in the market. Reed grows all over the world. It has a strong adaptability to the environment and can grow in rivers, ponds and swamps. At the same time, reed also has a strong reproductive ability, and several reeds will soon grow into reeds. The stem of reed grows upright in water. Its roots are very developed and deeply rooted in the soil. It has many branches, and there are many tiny branches and leaves under each branch. Reed can be used as firewood, and when the reed branches are mature or old, its surface is yellow. At this time, its branches are fragile, so you can take a long part of the sickle and cut it off, and the remaining part will grow green reeds in the coming year.
