From the color and shape, it is obvious that it is not a natural plant root.

Generally, ordinary tree roots or similar potato root blocks are used and processed by compression molding to form a human shape. It is also possible to make a mold first, and then transplant the plant into the human-shaped mold, allowing it to naturally grow into a human-shaped root mass. However, this takes more effort. And yours doesn't look like it either.

The first target of imitation is Polygonum multiflorum, and there are also those pretending to be ginseng.
