Traditionally, nopal (also known as prickly pear) has both food and medicinal uses. Nopals are common in North American deserts and are generally sold fresh, canned, or dried for use in the preparation of nopalitos (a traditional Mexican dish made from nopal pads). They have a light, tart flavor. Nopals are commonly used in Mexican and New Mexican cuisine in dishes such as huevos con nopales (eggs with nopal) or tacos de nopales. The juice is used in jellies and candies. The fruit is also eaten fresh or used in pies, deserts, shakes, or spreads.
Traditionally, nopal is medicinally used as an anti-inflammatory or a laxative. More recently, nopal has been used in exercise recovery and in reducing the symptoms of alcohol hangovers. Nopal is the most commonly used substance for lowering blood sugar among persons of Mexican descent.
EvidenceDISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
People who consume alcohol to the point of intoxication often experience what is known as a hangover, which can result in fatigue, headache, dizziness, and a general unpleasant feeling. Nopal may have hangover preventative effects, although more studies are needed to confirm this finding.
Diabetes is a chronic health condition where the body is unable to produce insulin and properly break down sugar (glucose) in the blood. Symptoms may include hunger, thirst, excessive urination, dehydration, and weight loss. Scientific studies suggest that nopal may decrease blood glucose levels in patients with type 2 diabetes.
Hyperlipidemia (high cholesterol):
Hyperlipidemia is described as excess levels of fats in the blood. Nopal may aid in reducing hyperlipidemia, although there is currently insufficient evidence to make a strong recommendation for this condition.
TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Acne, anti-inflammatory, antioxidant, antiviral, arthritis, astringent, benign prostate hypertrophy (enlarged prostate), burns, cardiovascular health, chest congestion, colitis, cuts, diarrhea, diuretic, exercise recovery, eye problems, hair tonic, hepatoprotection (liver protection), hypercholesterolemia (high blood cholesterol), hyperglycemia (high blood sugar), hyperlipidemia (high cholesterol), hypertension (high blood pressure), immunosuppression, insect bites, ischemic injury, laxative, obesity, platelet aggregation, rash, scrapes, skin irritations, skin toner, sunburn, ulcers, weight loss, wound healing.
Adults (18 years and older):
There is no proven effective dose for nopal in adults.
Children (younger than 18 years):
There is no proven effective dose for nopal in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid in individuals with a known allergy or hypersensitivity to nopal. Nasal inflammation or asthma has been reported due to allergy.
Side Effects and Warnings
Nopal is likely safe when used in food amounts, as nopal is common in Mexican and southwestern American cuisine.
Side effects associated with nopal may include mild diarrhea, nausea, abdominal fullness, headache, and increase in stool volume and frequency.
Use cautiously in individuals with rhinitis or asthma, as nopal may worsen symptoms.
Avoid in patients with immunosuppression, as nopal may suppress the immune system.
Avoid in patients with impaired liver function, as nopal may increase liver toxicity.
Pregnancy and Breastfeeding
Nopal is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
Interactions with Drugs
When mixed with water or other fluids, nopal forms a sticky, slippery gel. Taking nopal by mouth could block the absorption of drugs, other supplements, and nutrients from foods that are taken at the same time. Traditionally, patients are advised to not eat meals or take medication within two hours of consuming nopal by mouth.
Nopal may act as an acid absorber. Use cautiously with anti-ulcer medications.
Use of nopal and chloropropamide concomitantly may increase the hypoglycemic (blood sugar-lowering) effect and levels of insulin in patients with type 2 diabetes. Broiled nopal stems (not crude stems), nopal extract, or dietary cactus ingestion may lower blood sugar levels. Consult with a qualified healthcare professional as dosing may need to be adjusted.
Large doses of nopal may cause adverse effects on the liver and spleen.
Nopal may decrease lipids (fats) in the blood. Use cautiously in patients taking cholesterol-lowering medications due to possible additive effects.
Use cautiously with blood pressure-altering medications.
Although not well studied in humans, nopal may also interact with thyroid agents.
Interactions with Herbs and Dietary Supplements
When mixed with water or other fluids, nopal forms a sticky, slippery gel. Taking nopal by mouth could block the absorption of drugs, other supplements, and nutrients from foods that are taken at the same time. Traditionally, patients are advised to not eat meals or take medication within two hours of oral consumption of nopal.
Large doses of nopal may cause adverse effects on the liver and spleen. Use cautiously with herbs and supplements that may have similar effects.
Broiled nopal stems (not crude stems), nopal extract, or dietary cactus ingestion may lower blood sugar levels.
Nopal may decrease lipids (fats) in the blood. Use cautiously with cholesterol-lowering herbs and supplements due to possible additive effects.
Use cautiously with blood pressure-altering herbs and supplements due to possible additive effects.
Although not well studied in humans, nopal may also interact with thyroid agents. Use cautiously with herbs or supplements with similar or contradictory effects.
