Cashew is a tree. Its nut, also known as cashew, is commonly eaten as food. People also use the nut to make medicine.

Cashew is used for stomach and intestinal (gastrointestinal) ailments.

Some people apply cashew directly to the skin as a skin stimulant and to seal (cauterize) ulcers, warts, and corns.

How does it work?

Cashew contains chemicals that might work against certain bacteria.

Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

  • Metabolic syndrome. Early research suggests that eating a diet that contains a high amount of cashew does not improve blood pressure, blood fats, waist circumference, or body mass index (BMI) in people with metabolic syndrome. In fact, this diet might increase pre-meal blood sugar levels.
  • Stomach and intestinal disorders.
  • Skin ulcers, when applied to the skin.
  • Warts, when applied to the skin.
  • Corns, when applied to the skin.
  • Other conditions.
More evidence is needed to rate the effectiveness of cashew for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Side Effects

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.


Medications for diabetes (Antidiabetes drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Cashew might increase blood sugar when eaten in large amounts. Diabetes medications are used to lower blood sugar. Taking cashew along with diabetes medications might decrease the effects of diabetes medications. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.

Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.


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.
