The ‘paspanguwa’ traditional medicinal formula can be obtained as air-tight sachets or packets as an over-the counter medicine in pharmacies and supermarkets. The ailments, for which this can be used as per the instructions in the packaging, are colds, coughs, headaches, fever, and overall body aches. Although the herbal formulation itself has not been clinically evaluated, its constituents possess significant evidence as to their respective efficacies against a myriad of disease conditions. ‘Paspanguwa’ is commonly consumed as an herbal  tea  preparation. The name, which means five portions in the vernacular language of Sinhala, is made by the combination of five main herbs. The five ingredients, which make up the formula commonly, consist of  Ginger (Zingiber officinale), ‘Pathpadagam’ (Hedyotis corymbosa),

‘Katuwalbatu’ (Solanum xanthocarpum), ‘Veniwalgata’ (Coscinium fenestratum) and  Coriander  (Coriandrum sativum). In some instances other herbs such as ‘Thippili’ (Piper longum), Thai eggplant (Solanum melongena), Black pepper (Piper nigrum), Wishnukranthiya (Evolvulus alsinoides) and Pawatta (Justicia adhatoda)  may  also be used. Figure 1 shows a commercially available ‘paspanguwa’ package, and the ingredients used. The resulting herbal tea from this decoction is bitter in taste, thus, it is often taken together with sugar or juggery. To date, there has been only one in vitro study performed to explore the antioxidant and starch hydrolyses inhibitory properties of one form of the ‘paspanguwa’ herbal formula . However, it should be noted that the major constituents in these herbsin this herbal formula have been systematically studied for their efficacy against a variety of ailments, thus it may be deemed reasonable to review existing scientific material on these individual herbs. Overall, the purpose of this review is to describe the formula assess the ‘paspanguwa’ herbal formula and its constituents and  promote the argument whether scientific validation is truly required for traditional medicinal recipes, such as these, which have gained so much popularity even without the scientific rigor.

Traditional Methods of Preparation and Consumption of the ‘Paspanguwa’

There are several ways of preparing the ‘paspanguwa’ by locals as well as by traditional medicinal practitioners, where in all methods, addition of water and heat is the most frequent way of obtaining the extract.  Cold  water  may  be added to the ingredients until boiling temperature is reached, or boiled water may  be added to the ingredients and left in a closed container (typically, made from clay) for 10-15mins. The duration of boiling or exposure to boiled water may vary, mostly depending on the combination of ingredients used. The steam generated during the boiling process  may  also be used for inhalations to obtain relief from coughs and colds. The extract is recommended to be used at least 2-3 times per day, depending on the severity of the ailment. The traditional method of preparation has not been adequately documented and is passed down orally from one generation to another. Nevertheless, as one of the more ‘simpler’ forms of herbal formula in the traditional medicinal system of Sri Lanka, consultations with traditional medicinal practitioners revealed that the method of preparation does not vary all that much, other than the duration of boiling.

Quality of Preparation, Standards, and Dosages for Modern Times

One aspect of the ‘paspanguwa’ formula, if it were to be sent out to a global market, would be to enhance the quality of preparation, determine the standards and dosages a practice which has not been fully ascertained by modern day manufacturers of traditional medicines. The need for these aspects, especially Total Quality Management (TQM) has been emphasized in a recent publication by Cooper. While this paper focuses on Traditional Chinese Medicine (TCM), there is a need for all traditional medicinal systems to adapt to a more scientific means of verification, so that the health claims can be substantiated, including the ‘paspanguwa’ formula. Especially for Europe and the United States, acceptability of traditional herbal medicines requires evaluation of dosages to assure safety and efficacy. At this time, only a traditional medicinal practitioner’s word defines the currently accepted dosage of one ‘portion’ of each of the major herbs to varying amounts of the minor herbs, where ‘portion’ is simply a term of measurement of strength. For scientific investigations, researchers also need to bear in mind that the ‘paspanguwa’ formula is a combination of herbs, and thus, a reductionist approach may not work in fully determining its effectiveness. For this, modern advents such as use of a biomarker, linking a biological effect to a chemical marker and standardizing the levels of bio-actives, will go a long way to an improved quality product. Finally, newer processes such as systems biology, metabolomics and chemo metrics may be used to evaluate the biological responses of the formula more effectively, leading to a clinical trial.
