What others are reading
- n
- Postprandial (after meal) blood sugar reduction: A 2016 study found that insulin plant leaves helped reduce blood sugar spikes after eating in people with diabetes when combined with conventional treatments.
- Reduced insulin requirements: In another study, participants with insulin-dependent diabetes who consumed the plant leaves daily saw their insulin needs decrease by approximately half within just 15 days.
- Improved blood sugar levels: Individuals with poorly controlled diabetes, not on insulin but taking other diabetes medications, also reported better blood sugar management after consuming the plant for two weeks.
