Cytotoxic, antimitotic, and antiproliferation studies on Rasam: A South Indian traditional functional food

Abstract

Background:Rasam is a traditional South Indian food, prepared using tamarind juice as a base, with a variety of spices. Rasam, with all its ingredients medicinally claimed for various ailments, is a functional food. Systematic consumption of traditional functional food provides an excellent preventive measure to ward off many diseases.Objective:To study rasam for cytotoxic, antimitotic, and antiproliferation potential beyond its culinary and nutritional effect.Materials and Methods:Brine shrimp lethality assay, onion root tip inhibition assay, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay in Calu-6, HeLa, MCF-7 cell lines for four stage-wise samples in the preparation of rasam (RS1, RS2, RS3, and RS4) were studied.Results:RS4, the end product of rasam showed high lethality with an LC50 value of 38.7 μL/mL. It showed maximum antimitotic activity in a dose-dependent manner compared to other samples with an IC50 value of 189.86 μL/mL. RS4 also showed an IC50 value of 350.22 and 410.15 μL/mL in MCF-7 and Calu-6 cell lines, respectively.Conclusion:From this study, we suggest that rasam is a classic example of traditional functional food and it can treat breast and lung cancer on chronic use.SUMMARY Rasam, a South Indian traditional functional food, showed high lethality (LC50 = 38.7 mL/mL) against brine shrimpsRasam also showed potential antimitotic activity (IC50 = 189.86 mL/mL) by inhibiting the onion root tipsRasam showed an IC50 value of 350.22 and 410.15 mL/mL against MCF-7 and Calu-6 cell lines respectivelyRasam, when consumed on daily dietary basis, can treat breast and lung cancer.

An Updated Review on Medicinal Plants with Hepato-protective Activity

“…The liver cells receive blood from two different outlets. The hepatic artery transports oxygen-rich blood from the heart to the liver, while the portal vein transports nutrients from the intestine and spleen [4][5][6][7] .…”

“…As a result, over half of the treatments for liver illnesses currently originate from natural sources. Consistent conceptions of traditionally claimed medicinal plants for longer duration can achieve a therapeutic dose of the active ingredient/s 4 . The evidence that is now available also suggests that bioactive substances generated from therapeutic herbs may be potential hepato-protective agents.…”

A Review on <i>Rasam</i>: A Traditional Southern Indian Soup with Numerous Health Benefits

“…The IC 50 values for rasam against the MCF-7 and Calu-6 cell lines were 350.22 and 410.15 µL/mL, respectively. The findings indicate that rasam may have therapeutic activities against breast and lung cancer, although additional research is needed to determine this34 .…”
