What side effects this plant can have?

This plant can cause digestive issues such as flatulence, bloating, and abdominal discomfort due to its high concentration of complex oligosaccharides. These fermentable sugars are not easily broken down by human enzymes in the small intestine. Instead, they travel to the large intestine where gut bacteria break them down, producing gas as a byproduct. Some individuals may also experience nausea or stomach cramps if they consume the seeds without proper soaking or cooking. Ensuring thorough preparation is essential to minimize these gastrointestinal side effects.

According to a study published by "Plant foods for human nutrition (Dordrecht, Netherlands)", the hyacinth bean, known as Dolichos lablab, was ranked second in terms of oligosaccharide content or flatulence potential. This specific legume contained 3.66% total oligosaccharides. Regarding processing methods, soaking the batao seeds had no effect on these levels. Boiling the seeds actually resulted in a net 23-31% increase in the levels of raffinose, stachyose and verbascose. Alternatively, two min of dry roasting resulted in the complete removal of oligosaccharides. Germination led to a decrease of about 30-40% after 1 and 2 days, respectively.
