Maybe many of my friends have never heard of the information about Watson, and it is relatively new to Wasong. Watson is a biennial herb belonging to the genus Valeriana. It is also an alternate and thorny flower, and the flowering period is also around August-October. Watson is flat, acid has a certain toxin, can stop bleeding and can also be used for diarrhea and irregular menstruation. Appreciation value: Before and after the Duanyang Festival, its bulbs are long and the thumb is large. Even the roots are planted in small pots. It is very interesting to place on the balcony. Especially when it is tied with a wire, the bare suspension is suspended indoors, letting it grow into a U-shape, thus embellishing the interior, which is very unique. The scale of its scale is waxy and can protect the evaporation of water. In the dry season of water shortage, the water stored in its scale can also be used for the normal growth of stems and leaves, knowing its moisture. When it is finished, the wilting of the sphere completes its growth cycle. Studies have also shown that the plant extract has a certain inhibitory activity on liver cancer and gastric cancer cells, and the active ingredient is isopropylidene sedoheptanose. South Korea has conducted preliminary experimental research on the anti-cancer effect of Watson, but no results have been reported.
