Introduction: Acacia nilotica is otherwise called Babul is multipurpose nitrogen fixing tree legume. Its roots are beneficial in treating tumors, cancer, and tuberculosis. One of the most consumed beverages in the world, green tea (Camellia sinensis) has been researched for its potential health benefits in treating conditions like cancer, diabetes, obesity, heart disease, and neurological illnesses. The aim of this present study is to assess the combined effects of green tea and babul herbal formulation as an anti-inflammatory agent. Materials and Methods: Green tea and Babul extract was prepared. Albumin denaturation assay and egg albumin denaturation assay were used to assess the anti-inflammatory activity. Results: Both assays showed that Green tea and babul extract was effective in inhibiting the albumin denaturation at different concentrations. Conclusion: We conclude that green tea and babul herbal formulation can be a potent anti-inflammatory agent.

Background: Urolithiasis and nephrolithiasis are the commonly occurring painful diseases in most parts of the world. The number of new cases associated with lithiasis is on rise, although various therapies such as percutaneous nephrolithotomy, lithotripsy, and other surgical procedures can remove the stones, high recurrence rate is a major problem. Objectives: The present study was undertaken to evaluate the antilithogenic potential of green tea, oolong tea, and black tea employing chemical model. Materials and Methods: The antilithogenic action of different teas on calcium oxalate crystal formation was investigated on artificial urine spectroscopically, and the modulation of crystal size and density was recorded microscopically. Results: The different tea types showed significant inhibitory action on nucleation and crystal size morphology and density. The optical and spectroscopic techniques demonstrated that standard drug cystone exhibited highest inhibition followed by green tea, oolong tea, and black tea. Conclusion: Green tea illustrated maximum antilithogenic property as compared to other tea types and can be used as a potential dietary agent for the prevention of lithiasis.

The leaves of Vernonia amygdalina Del (Asteraceae) was processed into herbal tea using the black and green tea processing techniques. The green tea obtained was used as such while a portion of the black tea was flavored with O. basilicum or O. gratissimum. Methanol extracts of the flavored and unflavored herbal teas, obtained by cold maceration, were subjected to pharmacological studies for antihyperglycemic activity in alloxan diabetic rats and pytochemical analysis. Results showed that single oral administration of the tea extracts reduced blood glucose level of diabetic rats to varying the extents. Extract of green tea (GTE) caused a moderate reduction in blood glucose levels while black tea (BTE) evoked a mild dose-related effect. Extracts of the flavored tea caused significant (P\<0.05) reductions in blood glucose levels. While the effect of extract of O. basilicum flavored tea (BTOBE) was dose-related, that of O. gratissimum flavored tea (BTOGE) was non-dose-related. A comparison of the magnitude of reduction in blood glucose level showed the order of potency: BTOBE\>BTOGE\>GTE\>BTE. Phytochemical analysis showed relative presence of alkaloids, saponins, tannins, flavonoids, steroids and terpenoids with GTE having the highest concentration of these constituents. These findings suggest that black tea technique may be preferred for processing leaves of V. amygdalina into herbal tea since it preserved the antihyperglycemic activity. Green tea method may reduce the antihyperglycemic effect even though it preserves the phytochemical constituents better than black tea technique. Flavoring of black tea with Ocimum spp enhances the antihyperglycemic effect due to their inherent hypoglycemic activity.
