What is China officinalis?

China officinalis is a homeopathic remedy made from the bark of the cinchona tree. The bark is also called Peruvian bark or cinchona. Homeopaths give the remedy for weakness after heavy fluid loss, and for bloating and gas.

It is a single-drug remedy. That means one source plant, not a blend. The Latin name of the plant is Cinchona officinalis.

The remedy is made by watering the bark down again and again, with hard shaking at each step. At the common 30C strength, no bark is left in the pill or drop at all.

Tradition and proof are two different things. This remedy has a long place in homeopathic practice. But in trials it has not been shown to work better than a dummy pill, and long use is not proof that something works.

How does China officinalis work?

There is no accepted way this remedy could act on the body, because at 30C there is nothing of the plant left to act.

Homeopathy rests on two ideas. The first is that a substance which causes symptoms in a well person can treat like symptoms in a sick person. The second is that watering the substance down, with shaking, makes it act more strongly.

Neither idea fits what we know about chemistry or the body. Some homeopaths say the water holds a pattern or memory of the plant. No test has ever shown such a pattern, and trials do not separate the remedy from placebo (a dummy pill).

Any change you notice is most likely due to placebo effect, to the illness passing on its own, or to other care you are getting at the same time.

What forms does China officinalis come in?

The most common forms are sugar pellets and liquid drops.

Pellets are small and you let them melt under the tongue. Drops are usually made up in an alcohol base. Some makers also sell tablets and creams.

Labels show a strength, such as 6C, 30C or 200C. The higher the number, the more watering-down steps were used. At 30C and above, nothing of the bark is left.

A mother tincture is a different product. It is marked Ø or Q and is a plain bark extract. It still holds quinine, so the safety advice on this page matters most for that form.

Where it comes from:

Cinchona bark comes from South America. Quechua people used the bark for fevers and chills long before Europeans arrived. Spanish traders brought it to Europe in the 1600s, where it became the main treatment for malaria fever.

The remedy has a special place in homeopathy. In 1790 Samuel Hahnemann took doses of cinchona bark himself and wrote that it gave him fever-like symptoms.

That self-test led him to the idea of like treating like. It is counted as the first homeopathic proving, so China officinalis is one of the founding remedies of the tradition.

What does China officinalis help with?

• Weakness and tiredness after heavy fluid loss: This is the classic homeopathic picture for China officinalis, after sweating, diarrhoea, breastfeeding or blood loss. No human trial has tested the remedy for this. Heavy fluid loss needs real fluids, salts and medical care, so do not rely on the remedy in place of them.
• Bloating and trapped wind: Homeopaths pick it for a swollen belly that does not ease when you pass wind. This use rests on case reports and old texts, not on trials. There is no evidence it works better than a dummy pill.
• Fevers and chills that come and go: This use comes straight from the history of the raw bark as a malaria treatment. The homeopathic dilution is not a malaria treatment and contains no quinine. Malaria is life-threatening and needs proper drugs and urgent medical care.
• Headache that feels full or throbbing: Old homeopathic texts describe a heavy, bursting headache that feels worse from touch. No human trials support this use. A new, severe or unusual headache should be checked by a doctor.
• Ringing in the ears: Homeopathic texts list ringing in the ears among the remedy's symptoms, because large doses of raw quinine can cause it. That does not mean the diluted remedy treats it, and no trial has tested this.
• Night sweats: Traditional homeopathic use covers weakening sweats at night. There is no trial evidence. Ongoing night sweats can signal infection or other illness and deserve a medical check.

Which foods are rich in China officinalis?

1. Tonic water: holds a small, legally capped amount of quinine, the same substance found in the raw bark

Practical Tips:

Tonic water is a drink, not a treatment, and the homeopathic remedy is not found in any food.

What are the side effects of China officinalis?

• At 30C: no effects expected, since no plant matter is left
• Sugar pellets contain lactose (milk sugar), which can upset people who cannot digest it
• Alcohol-based drops can sting the mouth and are not suitable for everyone
• Short flare of symptoms that some homeopaths call an aggravation, which is not proven and may just be the illness itself
• From mother tincture or very low strengths: ringing in the ears, headache, nausea, blurred vision
• From mother tincture: skin rash and, rarely, a severe allergic reaction
• From mother tincture: easy bruising or bleeding from low platelets (blood cells that help clotting)
• From mother tincture: an irregular or racing heartbeat
• The real risk with any form: a delay in getting proper treatment for a serious illness

Good to know:

The 30C and 200C strengths are, chemically speaking, sugar and water, so direct harm from them is very unlikely.

The risk sits in two other places. One is the mother tincture and very low strengths, which hold real quinine and can cause the effects listed above. The other is using any homeopathic product instead of care that works for a serious problem such as malaria, sepsis or severe dehydration.

How much China officinalis should you take?

• Recommended daily: No dose has been shown to give a real effect, so there is no evidence-based amount to give. In common homeopathic practice, people take 3 to 5 pellets of a 30C strength, or about 5 drops, two or three times a day. Some practitioners give a single dose and then wait. A mother tincture is a different matter. It holds real quinine and should only be used under medical advice, if at all.
• Best time of day: There is no evidence that timing matters. Homeopaths often suggest a dose in the morning and one in the evening, at least 15 minutes away from food, drink, coffee or toothpaste.
• With or without food: Usually taken on an empty mouth, about 15 minutes before or after food or drink. This is a custom of the tradition, not a tested rule.
• Time to effect: There is no reliable time to effect, because trials do not show an effect beyond placebo. Homeopathic texts claim hours to a few days.
• How long to take it: Homeopaths usually suggest stopping once symptoms settle, and many stop after a few days if nothing changes. Do not keep taking it for weeks while a problem drags on. If your symptoms have not improved in 3 to 5 days, or get worse at any point, see a doctor instead.
