What side effects this plant can have?
This plant can cause favism in individuals with glucose-6-phosphate dehydrogenase deficiency, a genetic condition that leads to the destruction of red blood cells upon ingestion. This specific reaction occurs because the plant contains certain bioactive compounds that trigger oxidative stress within the bloodstream. Such oxidative damage can result in hemolytic anemia, characterized by jaundice, dark urine, and extreme fatigue. While the plant is a valuable source of protein, careful monitoring is necessary for vulnerable populations to avoid these acute hematological complications. Consuming unprocessed seeds may also pose risks due to the presence of naturally occurring anti-nutrients.
According to a study published by "The Journal of applied bacteriology", the toxic glycosides vicine and convicine present in Lablab purpureus have been implicated in favism, which is an anaemic disease of humans. These glycosides are identified as the components responsible for this condition. The concentrations of vicine and convicine can be reduced through the growth of Lactobacillus plantarum on Lablab purpureus suspensions. Additionally, the glycosides are eliminated from the Lablab purpureus substrate by the growth of the filamentous fungus Fusarium graminearum. Using a concentrated culture filtrate of Aspergillus oryzae can also result in the complete degradation of these glycosides.
The main side effects this plant can have are shown in the list below.
- favism
What herbs are paired with Lablab purpureus?
