Overview InformationCinchona is a tree. People use the bark to make medicine.
Cinchona is used for increasing appetite; promoting the release of digestive juices; and treating bloating, fullness, and other stomach problems. It is also used for blood vessel disorders including hemorrhoids, varicose veins, and leg cramps. Some people use cinchona for mild influenza, swine flu, the common cold, malaria, and fever. Other uses are for cancer, mouth and throat diseases, enlarged spleen, and muscle cramps.
Cinchona is used in eye lotions to numb pain, kill germs, and as an astringent. Cinchona extract is also applied to the skin for hemorrhoids, ulcers, stimulating hair growth, and managing varicose veins.
In foods, cinchona is used as a bitter flavoring in tonic water and alcoholic beverages.
How does it work?Cinchona bark contains quinine, which is a medicine used to treat malaria. It also contains quinidine which is a medicine used to treat heart palpitations (arrhythmias).
Uses & Effectiveness
Insufficient Evidence for
- Varicose veins.
- Leg cramps.
- Mouth and throat diseases.
- Enlarged spleen.
- Muscle cramps.
- Loss of appetite.
- Stomach discomforts, such as bloating and fullness.
- Other conditions.
Side Effects & SafetyCinchona is LIKELY SAFE when used as a flavoring in tonic water and alcoholic beverages.
Cinchona is POSSIBLY UNSAFE when taken by mouth as a medicine. Cinchona products sold as over-the-counter (OTC) medicines are required to carry the warning, “Caution - discontinue use if ringing in the ears, deafness, skin rash, or visual disturbances occur.“ Cinchona contains quinine, which was banned by the U.S. Food and Drug Administration (FDA) from sale over-the-counter for treatment of leg muscle cramps because it caused serious side effects.
In large amounts, cinchona is UNSAFE and can be deadly. Symptoms of overdose include ringing of the ears, headache, nausea, diarrhea, and vision disturbances. Cinchona can also cause bleeding and allergic reactions, including hives and fever.
Special Precautions & Warnings:Pregnancy and breast-feeding: Don’t use cinchona if you are pregnant or breast-feeding. There is some evidence that cinchona is UNSAFE to use during pregnancy and if you are breast-feeding.
Stomach or intestinal ulcers: Don’t use cinchona if you have ulcers. It might increase the risk of bleeding.
Heart conditions such as long QT interval syndrome: Cinchona contains quinine and quinidine that can cause an irregular heartbeat and might increase the risk of irregular heartbeat in people with long QT syndrome.
Myasthenia Gravis: Don’t use cinchona if you have myasthenia gravis. It contains quinine and quinidine that can cause muscle weakness and make your condition worse.
Surgery:Cinchona can slow blood clotting, so there is a concern that it might increase the risk of extra bleeding during and after surgery. There is also concern that quinidine in cinchona can increase the effects of muscle relaxants used during surgery. Stop using cinchona at least 2 weeks before a scheduled surgery.
Do not take this combination
Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs) interacts with CINCHONA
Cinchona might slow blood clotting. Taking cinchona along with medications that also slow clotting might increase the chances of bruising and bleeding.<br><nb>Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
Quinidine interacts with CINCHONA
Cinchona contains quinidine. Taking quinidine along with cinchona can increase the effects and side effects of quinidine and cause heart problems. Do not take cinchona if you are taking quinidine.
Quinine interacts with CINCHONA
Cinchona contains quinine. Taking quinidine along with cinchona can increase the effects and side effects of quinine and cause heart problems. Do not take cinchona if you are taking quinine.
Be cautious with this combination
Carbamazepine (Tegretol) interacts with CINCHONA
The body breaks down carbamazepine to get rid of it. Cinchona contains quinine. Quinine can cause the body to break down carbamazepine (Tegretol) too quickly. Taking cinchona along with carbamazepine (Tegretol) can decrease the effectiveness of carbamazepine (Tegretol).
Phenobarbital (Luminal) interacts with CINCHONA
Cinchona contains quinine. Quinine might increase how much phenobarbital (Luminal) is in the body. Taking cinchona with phenobarbital might increase the effects and side effects of phenobarbital.
Be watchful with this combination
Antacids interacts with CINCHONA
Antacids are used to decrease stomach acid. Cinchona may increase stomach acid. By increasing stomach acid, cinchona might decrease the effectiveness of antacids.<br><nb>Some antacids include calcium carbonate (Tums, others), dihydroxyaluminum sodium carbonate (Rolaids, others), magaldrate (Riopan), magnesium sulfate (Bilagog), aluminum hydroxide (Amphojel), and others.
Medications that decrease stomach acid (H2-Blockers) interacts with CINCHONA
Cinchona might increase stomach acid. By increasing stomach acid, cinchona might decrease the effectiveness of some medications that decrease stomach acid, called H2-Blockers.<br><nb>Some medications that decrease stomach acid include cimetidine (Tagamet), ranitidine (Zantac), nizatidine (Axid), and famotidine (Pepcid).
Medications that decrease stomach acid (Proton pump inhibitors) interacts with CINCHONA
Cinchona might increase stomach acid. By increasing stomach acid, cinchona might decrease the effectiveness of medications that are used to decrease stomach acid, called proton pump inhibitors.<br><nb>Some medications that decrease stomach acid include omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), pantoprazole (Protonix), and esomeprazole (Nexium).
The appropriate dose of cinchona 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 cinchona. 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.
