What Plant Is Black Nightshade? Understanding Its Morphology and Habits in One Article

Black nightshade is a relatively common plant. It can be seen by field edges, on wasteland, and near villages. Although black nightshade is very common, many people do not know what kind of plant black nightshade is.

1. What plant is black nightshade?

Black nightshade is an annual herbaceous plant in the Solanaceae family. The whole plant is 30-120 cm tall; the stem is erect and much branched; the ovate or heart-shaped leaves are alternate and nearly entire; in summer it bears small white flowers, 4-10 in a cyme; the berry is spherical and turns blackish purple when ripe. Both the berries and leaves can be eaten, but the leaves contain a large amount of alkaloids and must be cooked before they are detoxified. The whole plant is used as medicine and can dissipate blood stasis and reduce swelling, clear heat and remove toxin.

2. The growth habits of black nightshade

The suitable temperature for growth is 22-30°C, and the suitable temperature during the flowering and fruiting period is 15-20°C; at this temperature the fruit-setting rate is high. It has no strict requirements for soil and grows well on loam rich in organic matter with strong water and fertilizer retention. On clayey soil lacking organic matter and with poor aeration, the root system develops poorly, the plant grows weakly, and its market quality is poor. The suitable soil pH is 5.5-6.5. It is difficult to grow in the open field under high temperature and high humidity in summer and autumn. When planted in the open field in winter and spring, the plant grows slowly and the tender shoots easily become fibrous and aged, resulting in poor market quality. Therefore, to meet market demand, it can be cultivated in protected areas all year round.

3. The medicinal value of black nightshade

In fact, the medicinal value of black nightshade is still quite high. Basic functions such as clearing heat and removing toxin need not be emphasized repeatedly. In addition, for sprains and bruises that often occur in daily life, black nightshade can also have a very good therapeutic effect. Of course, for conditions such as some chronic tracheitis, taking medicines processed from black nightshade is also beneficial.

After black nightshade matures, it can be eaten as a fruit, and the whole plant can be used as medicine. Eating more black nightshade is very good for the body. However, black nightshade tastes a bit bitter, and children may not accept it.
