Side effects are common at high doses and may include mild diarrhoea, dizziness, constipation and bloating.
Allergies are rare but may occur.
Contraindications
The safety of white mulberry in children, pregnant and breastfeeding women has not been established. Given the lack of research, it is best to avoid using mulberry products in these groups.
Interactions
Due to its effect on blood sugar, white mulberry should be used with caution by people taking diabetes medication, including insulin. Combined use may cause a sudden drop in blood sugar (hyperglycaemia) characterised by tremors, dizziness, sweating, fatigue, lightheadedness and fainting.
The same may occur when blackberries are taken together with antihypertensive drugs used to treat high blood pressure. This can cause hypotension, where the rapid drop in blood pressure can cause fatigue, dizziness, clammy skin, blurred vision, nausea and fainting.
