To help with the cough, propolis is recommended, available in syrup form suited for children. Black seed oil will also be beneficial, and it can be mixed with juice as well as honey.
In addition, omega 3, 6, and 9, especially in syrup form, will help fight the allergy.
Finally, it will be important to get the child used to consuming black seed, juices, and fruits and vegetables to support vitamin C intake.
What the science says: cough, in children, allergies
What published research says about the remedies mentioned above, for context only — these studies look at material causes; healing belongs to Allah.
Cough
Honey is the best-proven remedy for cough: the Cochrane review finds it more effective than no treatment and comparable to common syrups in children (Cochrane, 2018) (Arch Pediatr Adolesc Med, 2007), and a meta-analysis evaluates traditional plants against cough (Forsch Komplementmed, 2015). Thyme, marshmallow root, plantain, inhalations, and humid air complete the picture. Precaution: no honey before age one; a cough lasting more than three weeks, with fever, blood, or shortness of breath, should be seen by a 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 cough (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.
Allergies
Saline nasal rinses, reducing allergens (dust mites, dust), and certain nutrients (quercetin, omega-3, vitamin D) reduce allergy symptoms; plants used in traditional medicine have been reviewed (Ther Clin Risk Manag, 2023) and black seed is being studied for its antiallergic action (Int J Mol Sci, 2024). Precaution: an allergic reaction causing facial swelling, breathing difficulty, or fainting is an emergency; asthma should be treated with your doctor, with natural remedies as a complement.
