Introduction

Prosopis juli ora(Sw.) DC, an invasive weed in India has been highlighted for its bioreme- diation and bioeconomic potentials (1). Prosopis juli ora attracted considerable negative criticism from a section of plant scientists for being an alien invasive species. However, itprovides a varietyof resourcesand additional income to the local people through  re- wood collection, coal production etc. besides bestowing health care services as well (see the exhaustive bibliography cited in (1). Plant based excipients play a key role in the for- mulation of e cient drug delivery mechanisms (Fig. 2) (2). Selected examples of popu- lar and better usedplantexcipient sourcesareas follows: Aloe vera (Xanthorrhoeaceae) as gelling agent, Anacardium occidentale (Anacardiaceae) as suspending agent, Anogeissus latifolia (Combretaceae) as binder, Boswellia serrata (Burseraceae) as natural suspend- ing agent, Buchanania axillaris (Anacardiaceae) as substitute of gum Arabic, Firmiana simplex (Malvaceae) as emulsifying agent, Senna tora (Fabaceae) as binder, Trigonella foe- num-graecum (Fabaceae) as gelling agent.
