'Paarshva-pippala' is an important drug mentioned in the traditional medicinal texts. However, two completely different species are used as 'Paarshva-pippala': Thespesia populnea (Malvaceae) and Ficus arnottiana (Moraceae). Recent pharmacological findings indicate that leaves of Thespesia populnea possess significant anti-diabetic activity and can be used in cutaneous infections, which comply with the claims made in the traditional medicinal texts regarding 'Paarshva-pippala'. However, no conclusive pharmacognostic study or phytochemical investigation of these leaves has been performed yet. The present work deals with the qualitative and quantitative pharmacognostic evaluation of the leaf material of Thespesia populnea and establishment of its quality parameters, including physicochemical and phytochemical evaluation. This would help in distinguishing Thespesia populnea from Ficus arnottiana and pave the way for isolation of phytoconstituents, therapeutic investigations and standardization of formulations containing its leaf material. Most importantly, it may shed light on the true botanical identity of 'Paarshva-pippala'.

Cordia dichotoma Linn (Family - Boraginaceae) is found commonly in India. Recent pharmacological findings indicate that its fruits possess significant activities like anthelmintic, diuretic, demulcent and expectorant, and are also used in disease of chest and urinary passage. A decoction of bark is used in dyspepsia and fever. These comply with the claims made in the traditional medicinal texts. However, no conclusive pharmacognostic study of its leaves has been performed yet. The present investigation deals with the qualitative and quantitative microscopic evaluation of the leaf material. Chief microscopic characters include vascular bundles having patches of perimedullary phloem and unicellular and multicellular covering trichomes. Chief characters of powder include anomocytic stomata, calcium oxalate prisms and clusters and xylem vessels with Reticulate thickening. Such a study would serve as a useful gauge in standardization of the leaf material, ensuring quality formulations, and distinguishing it from other species of Cordia.
