Both Radix Asparagi and Radix Ophiopogonis can nourish lung yin, moisten lung dryness and clear lung heat, and the difference between them is as follows. Asparagus and Ophiopogon japonicus, whose families and genera are different in the sky, are plants in the plant kingdom, which usually grow in shady places. For example, Ophiopogon japonicus is also cultivated in grass, mainly in East China. It belongs to Liliaceae, and most of them are distributed in Jiangxi, and their titles are different. There are many names for Asparagus, such as Tomorrow Winter, Astronomy East and so on. Although there are many names for Ophiopogon japonicus, it is completely different from Asparagus japonicus. Its names include Ophiopogon japonicus and so on, and their appearance is also different. Asparagus is a rock climbing plant, which will have many branches and hang down. Its length is about 12 cm, and its leaves are very flat and shaped like pine needles. There are also many thorns on its branches. Although these thorns are short, they are not very obvious. Its flowers are also white, and there are light green flowers. When they grow, there will be many fruits, which will turn red when they mature. Ophiopogon japonicus grow together in piles, and its height is about 3 cm. The leaves are piles that look particularly thin and long, and the color is dark green, which looks like leeks. There are also many words on the plant, its color is lavender, and there will be many fruits after the flowers fall, and then it will become dark green when the fruits mature. When treating diseases, asparagus is very cold, and it is mainly regulated by Ophiopogon japonicus, which is slightly cold. Although the effect of clearing fire is small, its moisturizing effect is also very good, so we must separate Tiantian from Ophiopogon japonicus when treating diseases, so don't confuse it.
