Silkworm excrement is a byproduct of silkworms spinning their silk; however, it is not as foul-smelling or dirty as many people think. Silkworms are very fragile creatures and cannot tolerate any kind of chemical treatment. Therefore, they only eat the freshest, greenest mulberry leaves. The Vu Thu region of Thai Binh province boasts lush green mulberry fields thanks to the fertile red alluvial plains of the Red River. The people of Vu Thu have a long tradition of mulberry cultivation and silkworm rearing. Silkworm excrement has many uses for humans. Let's list some of its benefits with Hanhsilk:
