Poultice study

There are a few members of the passionflower family (Passifloraceae) that have psychotropic effects. The one most studied is Pass flora incarnata, although some work has been done on Pass flora coerulea and Passiflora edulis. P. incarnata is a colorful, flowering plant with five white or lavender petals, a purple or pink corona, and five brightly colored stamen (Gruenwald et al. 1998). The parts of the plants used for medicinal effect are the whole plant or aerial parts. It is native to the mid- to southeastern United States. Passionflower has a history with Native Americans as a poultice to treat bruises, and as a tea for sedative/anxiolytic effects (Kowalchick and Hylton 1987). It is one of the most common herbs commercially available in Britain (Tyler 1994). 

Before the middle of the 1970s, a few synthetic polymers found applications in the pharmaceutical industry, such as polyvinyl pyrrolidone and polyvinyl alcohol for oral formulations, polyethylene glycol and polyethylene (PE) for ointments, and polyacrylic acid for poultice. Nowadays, following the development of the drug delivery system (DDS), more varied synthetic polymers are applied in formulation studies. Because DDS concentrates on increasing the therapeutic effectiveness of... 

Few human studies or clinical trials examining the potential health and/or therapeutic applications of rooibos have been reported. Dnring the early 1980s, a small (n=7) study was conducted in hnmans snffering from asthma or hay fever. Neither the ingestion of traditional rooibos nor the topical apphcation of a rooibos poultice exhibited any antihistaminic effects (75). Nearly a decade later, another human study was pubhshed that showed a positive effect an infusion of rooibos had on patients with atopic dermatitis and herpes simplex viral infection 74). A decreased itching and indnced-inflammation was reported as well as a decreased incidence of herpes simplex. As yet, no hnman studies on inunune responses have been published. 

Cryptotanshinone is a quinoid diterpene with a nor-abietane skeleton isolated from roots of the Iranian medicinal plant Perouskia abronatoides L. which exhibited leishmanicidal activity in vitro. These findings provide a rationale for the traditional use of the roots in Iran as a constituent of poultices for treatment of cutaneous leishmaniasis [199], More recently, Valderrama et al. [200] synthesized several eurylfurylquinones and hydroquinones from activated monosubstituted 1,4-benzoquinones and studied their in vitro activities against Leishmania amazonensis.
