 The seeds of a bruised precatorial cell, thabasi, commonly known as rati, have been traditionally used as a weight measure by indigenous people. However, the accuracy of these measurements has been questionable due to the variation in seed weight depending on age, moisture, and storage conditions. To validate the use of rati as a reliable weight measure, the seeds were subjected to various moisture conditions and monitored over time. Surprisingly, no change in seed weight was observed, suggesting that the seed coat is impermeable and thus protects the seed from external factors such as pests and microorganisms. This study also revealed the presence of a brine, a potent toxin, in the seed coat, which further strengthens its impermeability. Thus, the data suggests that the use of rati as a weight measure by indigenous people is valid and can be relied upon. This article was authored by Rajinder Kumar Sharma and Ali Bodhwa.
