Side Effects

Side Effects & Safety

Cashew is LIKELY SAFE in normal food amounts. There isn’t enough information to know if cashew is safe for use as a medicine. Unroasted cashew can irritate the skin and cause redness and blisters.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Cashew is safe when eaten as food, but there’s not enough information to know if it’s safe in the larger amounts that are used as medicine. If you are pregnant or breast-feeding, stick with food amounts until more is known.

Allergy to certain other nuts or pectin: Cashew might cause allergic reactions in people who are sensitive to hazelnut, Brazil nut, pistachio, almond, peanut, or pectin. If you have allergies, be sure to check with your healthcare provider before taking cashew.

Diabetes: There is some evidence that eating large amounts of cashew might increase blood sugar levels. If you have diabetes and use cashew, be sure to monitor you blood sugar carefully. The doses of your diabetes medications might need to be adjusted.

Surgery: Since cashews might affect blood sugar levels, there is some concern that it might interfere with blood sugar control during and after surgery. Stop eating large amounts of cashew at least 2 weeks before a scheduled surgery.



We currently have no information for CASHEW Interactions.



The appropriate dose of cashew for use as treatment depends on several factors such as the user’s age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for cashew. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
