Identification

Morphology

Justicia insularis is characterized by its distinct growth form as a self-supporting herb. This plant typically maintains a compact stature, reaching a maximum height of approximately 0.91 meters. While most specimens stay within this range, individual plants can vary significantly in size. Interestingly, observations of the species show height measurements spanning from a minimum of 0.30 meters to instances reaching up to 1.5 meters. This variability highlights the flexible physical presence of the species within its natural habitat.

Biological Activities

Justicia insularis is an edible and medicinal plant from Nigeria that shows significant potential in the field of oncology. Recent research has demonstrated that this species possesses notable cytotoxic activity, specifically targeting human ovarian cancer cell lines. Through bioassay-guided isolation, scientists identified two specific clerodane diterpenoids that drive this toxic effect. These compounds work by inducing apoptosis, or programmed cell death, within the cancer cells while remaining less harmful to normal ovarian surface epithelia. Consequently, the plant serves as a valuable natural source for discovering new hit compounds in the development of safer anticancer therapeutics.

Compounds

Conditions

Justicia insularis is traditionally used to treat dysmenorrhea and regulate the menstrual cycle in women. Research into its chemical components, specifically clerodane diterpenoids, demonstrates that the plant treats OVCAR-4 and OVCAR-8 cancer cell lines by inducing apoptosis. In studies involving follicular development, the extract shows a neutral effect on ROS levels, maintaining them without significant differences compared to control groups. Furthermore, the plant improves reproductive outcomes by increasing the viability of resulting oocytes compared to follicle-stimulating hormone. These diverse biological activities highlight the plant's potential as both a medicinal treatment and a functional alternative in reproductive science.

Preparations

Justicia insularis is prepared as an aqueous extract to facilitate the growth of preantral follicles in sheep and to induce ovarian folliculogenesis in rats. This plant is also prepared as a plant extract for the purpose of evaluating cytotoxic compounds and clerodane diterpenoids against human ovarian cancer cells. Furthermore, Justicia insularis is prepared as an extract to serve as a potential, cost-effective alternative to commercial follicle-stimulating hormone in in vitro culture media. In certain traditional medicinal concoctions, the species is prepared as a leaf mixture extract alongside other plants to improve fertility and regulate menstrual cycles.

Parts used

Justicia insularis is a medicinal plant primarily valued for the therapeutic properties found within its leaves. In the Western Region of Cameroon, the leaves of this species are combined with other plants to create a concoction used to regulate menstrual cycles and treat infertility. Scientific research has specifically focused on the aqueous extract of these leaves to evaluate its impact on reproductive health. Studies indicate that the leaf extract can significantly induce ovarian folliculogenesis and increase the production of estradiol. Consequently, the leaf serves as a critical component in traditional herbal remedies aimed at improving female fertility.
