Yes, a child with diabetes can indeed consume olive leaf, though they should take half the amount taken by an adult—that is, ten leaves infused for fifteen minutes.
They should consume this once a day in a small glass, and must be older than two years old.
What the science says: olive oil and olive leaf, diabetes and blood sugar, in children
What the published research says about the remedies mentioned above, for context — these studies deal with material causes; healing belongs to Allah.
Olive oil and olive leaf
"Eat olive oil and apply it to your skin": a 2022 meta-analysis links olive oil consumption to a reduction in cardiovascular risk, type 2 diabetes, and mortality (Clin Nutr, 2022). Olive leaf, for its part, has shown an effect on blood pressure and metabolic profile in prehypertensive individuals (PeerJ, 2021) (Phytomedicine, 2011). Precaution: olive leaf extract potentiates antihypertensive treatments — monitor your blood pressure and discuss it with your doctor.
Diabetes and blood sugar
Diet (low glycemic index, fiber, fewer fast-absorbing sugars) is the foundation of type 2 diabetes treatment (BMJ, 2021); several plants from tradition — cinnamon, fenugreek, black seed, turmeric, olive leaf — have a blood-sugar-lowering effect confirmed by meta-analyses (Diabetes Metab Syndr, 2023) (Nutrients, 2024), and camel milk is being studied in this context. Precaution: these remedies are added on top of treatment and can cause hypoglycemia if combined with it — monitor blood sugar and never change an insulin dose without the doctor.
In children
In infants, the probiotic Lactobacillus reuteri reduces colic-related crying according to a meta-analysis (Pediatrics, 2018) (Acta Paediatr, 2024); in children, honey soothes nighttime coughing (after age one) (Cochrane, 2018), fiber and hydration treat constipation (J Pediatr, 2022), and omega-3s are being studied for hyperactivity (Neuropsychopharmacology, 2018). Precaution: never give honey before age one, no essential oils before age 3 (age 6 for peppermint), doses adjusted to weight; any fever in an infant under 3 months is an emergency.
