From the age of 2, a child can consume black seed and propolis.
As for infants, they can take black seed in the form of cereals suited to their young age, and propolis that has been laboratory-processed and blended with other plants so that it is safe for the baby.
What the science says: for children, propolis, royal jelly and hive products, spirulina
What published research says about the remedies mentioned above, for context only — these studies look at material causes, while healing belongs to Allah.
For children
In infants, the probiotic Lactobacillus reuteri reduces colic 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.
Propolis, royal jelly and hive products
Propolis, a resin gathered by bees, shows healing effects confirmed by a meta-analysis on skin wounds (Arch Dermatol Res, 2023) and benefits for oral health (J Funct Biomater, 2024). Like honey, these products are part of the apitherapy that the professor recommends to support immunity. Precaution: possible allergy to hive products (especially propolis and bee pollen) — start with small amounts; bee venom should only be used with a trained professional.
Spirulina
Spirulina improves lipid profile according to a network meta-analysis comparing nutraceuticals (Pharmacol Res, 2022) and is among the supplements evaluated for weight (Pharmacol Res, 2023); rich in protein, iron and beta-carotene, it supports people who are tired or deficient. Precaution: require a controlled source (risk of contamination by heavy metals or toxins); not recommended in cases of phenylketonuria or active autoimmune disease without medical advice.
