What are the morphological characteristics of this plant?
Dichrostachys cinerea has pinnate leaves consisting of numerous small, oblong leaflets arranged along a central axis and small, woody, bipinnate flowers that produce long, silky, yellowish-brown stamens. The plant typically grows as a spreading shrub or small tree with dark, fissured bark. Its leaves are arranged alternately on the stems and provide a dense, feathery texture to the canopy. The characteristic flowers are arranged in globular heads that appear at the ends of branches. After flowering, the plant develops distinctive, flattened, woody seed pods that are often curved or twisted in shape.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of sub-Saharan Africa, stretching from Senegal in the west to Ethiopia in the east and southward to South Africa. It is commonly found throughout the savannas, woodlands, and scrublands of countries such as Kenya, Tanzania, Zimbabwe, and Nigeria. The species thrives in various habitats, including disturbed areas, riverbanks, and open grasslands where light is abundant. Because it can tolerate diverse environmental conditions, it often establishes itself in regions characterized by seasonal rainfall and warm temperatures. Its widespread presence across the continent makes it a significant component of many African ecosystems.
How is this plant cultivated?
This plant is cultivated in tropical and subtropical regions by planting seeds directly into well-drained, fertile soils under full sunlight.
It thrives best in warm climates and requires minimal irrigation once its deep root system is established. Gardeners often use this species for land reclamation or as a hardy hedge due to its ability to tolerate poor soil conditions. Because it grows rapidly, regular pruning is necessary to manage its size and maintain its structure.
Proper drainage is the most critical factor to prevent root rot during heavy rainy seasons.
What parts of this plant are used medicinally?
This plant Dichrostachys cinerea is utilized medicinally through its bark, fruit, leaves, roots, and the whole stem. The bark is frequently processed to treat various ailments, while the leaves are often prepared as decoctions for their healing properties. The fruit serves specific therapeutic roles in traditional practices, and the roots are harvested to address diverse health concerns. Additionally, the whole stem can be employed in medicinal preparations to target different physiological issues. These various components collectively provide a broad spectrum of traditional remedies.
According to a study published by "Journal of ethnopharmacology", the barks of Dichrostachys cinerea are traditionally used by Gabonese and Ivorian populations to treat rheumatism, bronchial asthma, and other various diseases. These barks are also used to facilitate childbirth, a use supported by findings where methanolic extract concentrations of 3.2µg/ml, 16µg/ml, 80µg/ml, 400µg/ml, and 2mg/ml were studied on isolated uterine smooth muscle. The study observed a contraction amplitude of 30.41mN (12%) at 80µg/ml and an amplitude of 39.68mN (14.17%) at 400µg/ml for Dichrostachys cinerea. These results were compared to oxytocin concentrations of 8.4×10(-5)µg/ml, 8.4×10(-4)µg/ml, 8.4×10(-3)µg/ml, and 8.4×10(-2)µg/ml. While an oxytocin concentration of 8.4×10(-3)µg/ml induced contractions of 45.82mN, the highest concentration of 8.4×10(-2)µg/ml induced contractions of 55.82mN.

Aqueous crude extracts from different plant parts of this species were evaluated for their in vivo antimalarial activity using Plasmodium berghei infected Swiss mice. The screened crude plant extract of Dichrostachys cinerea (L) Wight et Arn suppressed parasitemia by 6.3%. Regarding toxicity, the root extract of Dichrostachys cinerea had an LC50 > 1000 µg/ml and was therefore considered to be non toxic. The study also noted that the plant parts are used in combination with others to treat malaria.

According to a study published by "African journal of traditional, complementary, and alternative medicines : AJTCAM", the leaves of Dichrostachys cinerea Linn (LDC) were screened for anti-inflamatory activity using a carrageenan-induced rat paw oedema test. A modified traditional method of crude saponins extraction produced a percentage yield of 1.62% for LDC. The acute toxicity study in mice determined an intraperitoneal LD50 of 1264.9 mg/kg for the LDC crude saponin extract. This extract showed a statistically significant (P<0.05) decrease in rat paw-oedema compared to the control. After four hours, the percentage inhibition of the LDC extract was 72%, which was comparable to the 63% value of ketoprofen.

According to a study published by "Analytica chimica acta", Dichrostachys cinerea is one of the plant species used for the treatment of perceived HIV and AIDS-associated opportunistic infections by traditional healers in Ngamiland District in Northern Botswana. The study determined that this medicinal plant contained heavy metals in varying quantities, specifically arsenic at 0.19-0.54 μg g(-1), chromium at 0.15-1.27 μg g(-1), lead at 0.12-0.23 μg g(-1), and nickel at 0.09-0.21 μg g(-1) of dry weight. All of these determined metals were found to be below the WHO permissive maximum levels. Furthermore, the possible maximum weekly intakes of these heavy metals following treatment regimes were insignificant compared to the provisional tolerable weekly intake levels recommended by WHO and the Joint FAO/WHO Expert Committee on Food Additives. This indicates that heavy metal exposure to patients from consuming these traditional medicinal plant preparations remains within non health-compromising limits.

According to a study published by "Malaria journal", the dichloromethane extract of Dichrostachys cinerea (whole stem) exhibited cytotoxicity in a monkey kidney epithelial cell line with a CC50 of 29.44 µg/mL. The dichloromethane extracts of Dichrostachys cinerea (stem bark) showed promising in vitro anti-malarial activities against chloroquine sensitive (D6) and chloroquine resistant (Dd2) strains of Plasmodium falciparum. These stem bark extracts also exhibited significant anti-malarial activities in a mouse model, showing a parasite suppression rate of 53.12%. In addition to this suppression, the extracts contributed to a considerable improvement in weight and survival rate. Phytochemical screening of Dichrostachys cinerea extracts revealed the presence of flavonoids, tannins, steroids, triterpenoids, glycosides, and saponins, though alkaloids were absent in most extracts.
