Nutritional and Therapeutic Potential of Cassia fistula Pods: A Comprehensive Study on Mineral Composition, Immunomodulation, Antidiabetic Benefits, and Safety of Amaltas Tea in Southeast Punjab, Pakistan

TL;DR

This study explores the health benefits of Cassia fistula pods, showing they are rich in minerals and may help lower blood sugar and boost immunity safely.

Contribution

The study provides new evidence on the antidiabetic, immunomodulatory, and safe use of Cassia fistula pod-based tea.

Findings

Cassia fistula pods contain significant amounts of copper, iron, manganese, and zinc.

The tea showed high inhibitory activity against α-glucuronidase and reduced blood glucose in animal models.

It demonstrated immunomodulatory effects and no toxicity in tested animals.

Abstract

Cassia fistula, a plant belonging to the Leguminosae family, grows in various regions, including South Africa, Asia, China, America, Canada, Bangladesh, Afghanistan, Pakistan, Brazil, and West India. Southeast Punjab, Pakistan, has long utilized
C. fistula
tea, which is becoming more popular due to its high mineral content, phytochemical compounds, and possible medical properties. This study investigates how to improve immunity, control diabetes, and ensure that it is safe to use. Knowing its makeup and effects might help justify its use in functional tea. The pods of
C. fistula
have been found to possess antidiabetic, anti‐enzyme, and immunomodulatory properties, as demonstrated by various tests. This work focuses on assessing properties and mineral profile analysis using the Association of Official Analytical Chemists standard protocol. The brine shrimp lethality method was employed to evaluate
C. fistula
pod‐based functional toxicity. Results of mineral contents demonstrated that copper (0.08 ± 0.03 ppm), iron (0.44 ± 0.01 ppm), manganese (0.14 ± 0.01 ppm), and zinc (0.27 ± 0.01 ppm) are present, enhancing the nutritional values of the pods. The functional tea from
C. fistula
pods showed the highest percentage of inhibitory activity against α‐glucuronidase, with a percentage of 60.66%, followed by β‐glucuronidase, α‐glucosidase, and α‐tyrosinase. According to immunomodulatory and toxicity studies, animals treated with
C. fistula
pod‐based functional tea showed lower blood glucose levels, increased serum antibody titer, and safety for human health.
C. fistula
pods, rich in minerals, have potential nutritional and therapeutic benefits, making Amaltas tea a safe and effective natural remedy in Southeast Punjab.

Functional tea from
C. fistula
's pod possesses a good amount of minerals, including copper, iron, manganese, and zinc in non‐toxic concentrations, and showed the highest percentage of inhibitory activity against α‐glucuronidase. It also further showed lower blood glucose than the control group in an animal model with higher immunomodulatory activity and no toxicity.
