Yam bean can be harvested and planted directly, but it will take two years to really harvest yam. Because yam bean was planted in the first year, the yam seeds harvested by the end of 10 were not long and thin (about 20 cm) and could not be eaten. What can I say? It's not delicious. Only when this yam is planted in the next spring can it be harvested, which is really delicious.

3. Dioscin in yam bean can synthesize hormones, such as testosterone and estrogen, so it is not suitable for male patients with prostate cancer and female patients with breast cancer.
