BACKGROUND AND OBJECTIVE: Tiryaq-i-Afayee, a polyherbal formulation of Unani medicine used in the prevention and treatment of various wabāi amrād (epidemic/ pandemic diseases) since olden days. This review study has been carried out to explore the therapeutic efficacy of this formulation in the light of scientific studies. MATERIALS & METHODS: A total of 74 literature comprising classical Unani texts from the period of 9th – 20th century AD, and published research articles in various reputed journals from 1999 – 2020 AD were reviewed regarding immunomodulatory, antiviral, antiinfluenza, antioxidant, antitussive, antimicrobial effects of Tiryaq-iAfayee, as a whole preparation and its individual ingredients. RESULTS:Tiryaq-i-Afayee contains Sibr Zard (Aloe vera) (2 parts), Murr Makki (Commiphora myrrha) (1 part) and Zafran (Crocus sativus) (1 part). It is prepared in the form of pill, and 2 g is used in alternate day for prevention and management of epidemic diseases. All the three ingredients of this compound formulation belong to plants and individually used for various medicinal purposes. DISCUSSION: A study revealed that Tiryaq-i-Afayee possesses significant immunomodulatory effect in a small group of immuno compromised persons. An ethanol extract of Aloe vera exhibited antiinfluenza effect against influenza A virus due to presence of aloe-emodine (anthraquinone glycoside). Certain studies have reported that Commiphora myrrha possesses significant antioxidant and antimicrobial effects against Staphylococcus aureus and Pseudomonas aeruginosa. Another study has revealed that Saffron extract exhibited promising antiviral activity due to presence of crocin and picrocrocin. CONCLUSION: The aforementioned classical and modern conventional materials have given plentiful information regarding use of Tiryaq-i-Afayee in the prevention of epidemic/ pandemic diseases.

 Objectives: The objectives of the study were to examine the inhibitory effect of ethanol extract of Eriobotrya japonica leaves (EEEJL) pre-incubated with theophylline and aspirin on isolated guinea pig tracheal chains against acetylcholine (ACh)-induced contraction.Methods: The effect of EEEJL (1-8 mg/Ml) on the isolated tracheal strips was tested in vitro. Furthermore, the mechanism of relaxant effects of EEEJL was evaluated in the presence of theophylline and aspirin.Results: The contractile response evoked by Ach (1.25 × 10−3 M) was decreased by EEEJL (effective concentration50 = 1.36 mg/mL) and has no significant difference of relaxant effect to that of EEEJL pre-incubated with theophylline and aspirin (p>0.05).Conclusion: The EEEJL decreased the ACh-induced contraction through the inhibition of PDE and the protective effect on prostaglandin E2.

Coronary flow was recorded from spontaneously beating isolated perfused hearts of rats and guinea pigs. Arachidonic acid (AA), in single bolus doses, produced a fast short lasting coronary constriction followed by a slow developing but persisting vasodilation. These reactions (biphasic type) were characteristic of the guinea pig heart. In about 50% of the rat hearts the vasoconstrictor action predominated while the biphasic response was obtained in the rest of the experiments. Pretreatment of rats with aspirin prevented the responses to AA in the isolated heart. The administration of reduced glutathione (GSH) (about 1 mM to the rat or 0.5–0.75 mM to the guinea pig hearts) produced a marked development and (or) enhancement of the vasodilator action of AA. Repeated or single large doses of AA produced a change of pattern of responses from biphasic to constrictor type; the addition of GSH restored the vasodilator phase. Since GSH directs the endoperoxide metabolism towards the synthesis of prostaglandin E2 (PGE2), we postulate that the coronary dilatation of resistance vessels produced by AA would be due to a great extent to PGE2.
