Because of seasonality, flowers bloom in March and April, fruits mature in June and July, and plants dry up after 10.

There is a proverb called March 3, and shepherd's purse is a panacea. At this time, the flowers of shepherd's purse are relatively small, with 4 petals, white or light yellow, sweet temperature and faint fragrance.

Shepherd's purse itself contains a small amount of sodium sulfite, which is slightly toxic. After blanching, oxalic acid and sodium sulfite are removed. In this way, we can safely enjoy the boiled shepherd's purse.
