A Complete Picture Gallery of Gua Zi (Trichosanthes Seeds) to Help You Recognize Their Morphological Features

Gua Zi are the seeds of the Gua plant, a climbing vine in the Cucurbitaceae family. The Gua plant is what is traditionally known as Trichosanthes kirilowii (Chinese snake gourd), named because its fruits hang downward as they mature on the vine. Searching online for Gua Zi images usually turns up two types: one is the raw, dried seed with its shell still on, and the other is the roasted, seasoned finished product.

From the images, shell-on Gua Zi mostly appear as flat ovals, slightly pointed at one end, with shells ranging mainly from grayish brown to light brown and often bearing natural fine lines on the surface. Once the shell is cracked open, the kernel is pale yellow-green, plump and glossy. Roasted Gua Zi are darker in color, and some have a light coating of salt crystals on the surface, which is also the source of the whitish sheen seen in many photos.

When identifying Gua Zi from images, pay attention to a few details: whether the shape is neat, whether the size is uniform, whether the shell shows obvious damage or mold spots, and whether the color looks natural and consistent. Gua Zi have thin shells and large kernels with a crisp, fragrant taste. They are a common snack nut and often appear on fruit platters for entertaining guests during festivals, so images of them frequently show them loose or in packaging.

It is worth noting that Gua Zi, watermelon seeds and sunflower seeds come from completely different plants, and when images of the several are placed side by side, they are not hard to tell apart by shape and color. In addition, online images may have color deviations or post-processing, so slight differences in the actual color are normal. When choosing, it helps to look at images from different angles and combine them with the product description to judge quality overall.
