Do not self-treat with Ding Gong Teng
If this is an emergency
Some reactions to Ding Gong Teng need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Who should avoid Ding Gong Teng?
- Do not use if you are pregnant, trying to get pregnant, or breastfeeding. This ban is absolute, in any form, on the skin or by mouth.
- Do not use if you have asthma or COPD (a long-term lung disease), because it can tighten your airways.
- Do not use if you have a slow pulse (bradycardia), heart block, or a pacemaker.
- Do not use if you take neostigmine, pyridostigmine, donepezil or rivastigmine, or any other drug for myasthenia gravis (a muscle weakness illness) or dementia.
- Do not use if you take a beta blocker, digoxin, diltiazem or verapamil for your heart.
- Do not use if you have a peptic ulcer (a sore in the stomach lining) or long-term stomach pain.
- Do not use if you have a blockage in your gut or bladder, or trouble passing water.
- Do not use if you are giving it to a child or an older frail adult.
- Do not use if you have glaucoma (high pressure inside the eye) unless your eye doctor has cleared it.
- Do not use if you have broken skin, a cut or a rash where the wine would go.
- Do not use if you plan to drink alcohol, drive or use machines that day.
- Never put the herb, the tea or the wine in or near your eyes.
When should you see a doctor?
Stop the herb and call a doctor the same day if you sweat heavily, drool, feel sick, or feel your pulse slow down.
Get emergency help now if you have trouble breathing, chest tightness, a very slow or pounding heart, non-stop vomiting, blurred sight, confusion or fainting. Take the bottle or packet with you so staff can see what you took.
Also see a doctor if joint pain lasts more than two weeks, wakes you at night, or comes with fever, swelling or weight loss. Those need a diagnosis, not a rub.

What is Ding Gong Teng?
Ding Gong Teng is the dried woody stem of a climbing vine from southern China. It is also known as Erycibe Stem. It is used as a single herb, mainly for stiff, aching joints and for pain after a fall or sprain.
Most often the stem is soaked in rice wine. The wine is rubbed on the sore area, or taken in very small amounts by mouth. It is also boiled into a tea or added to shop-bought rubs for joint pain.
This is not a gentle herb. China lists it as toxic, and too much causes heavy sweating, a slow pulse and vomiting. Human trial evidence is very thin, and long use in a tradition is not proof that a herb works.
How does Ding Gong Teng work?
The main idea is that this herb makes certain nerve signals stronger. Its key compound acts like acetylcholine, a body chemical that tells glands and smooth muscle to switch on.
That is why it can make you sweat, make your pupils small and slow your heart. In Chinese medicine this is described as moving wind and damp out of the joints and channels.
How this would ease joint pain in people is not clear. Most of what we know comes from lab dishes and animals, not from people. Treat the idea as a theory, not a proven path.
What forms does Ding Gong Teng come in?
You may meet Ding Gong Teng in these forms:
- Dried sliced stem, boiled into a tea (decoction). - Medicated wine rubbed on the skin, which is the most common form. - Medicated wine taken by mouth in very small measured amounts.
- Ready-made rubs, plasters and patent pills for joint pain, where it is one herb among many. - Eye drops made in China from the isolated compound baogongteng A.
The eye drops are a prescription product, not a home remedy. They are not the same thing as the herb.
Where it comes from:
Ding Gong Teng comes from folk use in Guangdong, Guangxi and nearby parts of southern China. Village healers soaked the stem in wine for wind-damp pain, which is the old term for joint pain that is worse in cold, wet weather.
It is a fairly late arrival in the written Chinese materia medica and was added to the Chinese Pharmacopoeia in the modern era. It is listed there with a toxic warning.
What does Ding Gong Teng help with?
- Joint pain and stiffness blamed on cold, damp weather: This is the main traditional use. Healers rub the medicated wine on the sore joint, often with heat, and expect warmth and easier movement. We found no good human trials of the herb for arthritis or any other joint disease. So this use rests on tradition and on lab work, not on tested proof in people.
- Low back and leg pain: Old use covers aching legs and low back pain that drags on in damp weather. The wine is rubbed in; sometimes a small dose is drunk. There is no tested human evidence for this. Back and leg pain has many causes, some serious, so get a diagnosis before treating yourself.
- Bruises, sprains and pain after a fall: Ding Gong Teng appears in many Chinese trauma wines and rubs used after knocks and sprains. Only put it on skin that is not broken. Never pour the wine into an open cut or graze. The evidence here is traditional use only.
- Muscle aches with a feeling of heaviness: In Chinese medicine, heavy, sore limbs point to damp. This herb is one of the choices for that picture. No human trials back this up. It is a way of sorting symptoms, not a tested treatment.
- Glaucoma (high pressure inside the eye) - isolated compound only: Drops made from the single compound baogongteng A have been used in China to make the pupil smaller and lower eye pressure. That is a lab-made drug product under a doctor's care. Do not put the herb, the tea or the wine anywhere near your eyes. Glaucoma can steal your sight, so it needs an eye doctor.
What are the side effects of Ding Gong Teng?
- Heavy sweating, sometimes soaking
- Extra spit, watery eyes and a runny nose
- Feeling sick, vomiting, belly cramps or loose stools
- Slow pulse and a faint or light-headed feeling
- Small pupils and blurred vision
- Weakness and shaky legs
- Tight chest or wheeze, most of all in asthma
- Needing to pass water more often
- Skin rash, redness or itch where the wine was rubbed in
Good to know:
Sweating is the classic sign that you have taken too much, and it comes on fast. Mild sweating and a dry mouth feeling may pass within hours once you stop.
The serious end is a slow pulse, breathing trouble, non-stop vomiting or confusion. That is poisoning and needs emergency care, not a wait-and-see. Deaths from tropane-type plant poisoning are rare but real, so respect the dose.
