Pharmacological Potential of Jasminum auriculatum Extracts Ointment as an Anti Psoriatic Agent: In vivo Evaluation Using Swiss Albino Mice Model

Synthetic drugs are the drug of choice for topical treatment of psoriasis. However, these are associated with side effects; hence, there is a need to explore effective alternative treatments for psoriasis. Jasminum auriculatum has been used in Ayurvedic and traditional medicine as an ingredient for managing numerous skin ailments like eczema and ringworm.

This study aimed to evaluate the in vivo study of ointments prepared from chloroform and methanolic extracts of Jasminum auriculatum for the treatment of psoriasis.

Initially, pharmacogenetic and physicochemical characterization of Jasminum auriculatum was performed to check their presence. The ointments prepared from chloroform and methanolic extracts of Jasminum auriculatum were screened for acute toxicity studies and antipsoriatic activity by IMQ-induced psoriasis in the Swiss albino mice ear model. The parameters like ear thickness, ear weight, erythema, scales, and infiltration (Permeation into the skin) were evaluated. The histopathological studies were also conducted to support the findings.

The plant showed the presence of pharmacogenetic structures like Trichomes, Palisade cells, Xylem, Collenchyma Tous cells, Parenchymatous cells, Fibers, Pericyclic cells, Stomata, Phloem, and Sclerenchyma Tous cells responsible for the presence of phytoconstituents having antipsoriatic activity. The signs and symptoms increased in imiquimod-induced animals, but ointment of chloroform and methanolic extract of Jasminum auriculatum reduced the skin thickness, redness, scaling, and erythema. The study reveals along with the progression of disease topical formulation of the extract showed the effect on animals in a dose-dependent manner. Histopathological examination also supported the earlier results.

The present study demonstrates that ointments of chloroform and methanolic extract of Jasminum auriculatum are safe and effective in the treatment of psoriasis, as revealed by the in vivo study. These preclinical results could further be explored for the development of other topical formulations used in humans.
