Back to Traditional Chinese Medicine (TCM)Stroke is an emergency: call 911 first
Face drooping, one arm that cannot be lifted, or slurred or confused speech are stroke signs. The NHS uses the word FAST (face, arms, speech, time to call for emergency help). [1] In the US, call 911 immediately. Symptoms can stop after a short time, but even then get medical help straight away. [1] No herbal product, acupuncture session or other traditional treatment should delay emergency care. This page is about recovery and memory conditions after the emergency is over.What this page covers
Acupuncture for stroke has been used in China for hundreds of years and is increasingly practiced in some Western countries. [2] This page reports what Cochrane and other reviews found for specific interventions, not for "TCM" in general. NCCIH says Chinese herbal products have been studied for stroke, heart disease and other conditions, but that because many studies were poor, no firm conclusions can be made. [3]Stroke recovery
| Intervention | What the source found | Strength of evidence |
|---|---|---|
| Acupuncture for subacute or chronic stroke | Cochrane review of 31 trials (2,257 people); quality low or very low. Two trials compared real with sham acupuncture and found no differences in motor function or quality of life. Trials versus no acupuncture favored acupuncture on several measures, but the authors said there was inadequate evidence to draw conclusions about routine use. [2] | Insufficient evidence (sham comparison showed no difference) |
| Mailuoning (herbal injection or oral liquid) for acute ischemic stroke | Cochrane review of 21 trials (1,746 people); 20 were of poor quality. The one better-quality placebo-controlled trial did not show significant improvement in neurological deficit. The review did not provide sufficient evidence for routine use. [4] | Insufficient evidence |
Acupuncture itself is explained in What is acupuncture?, with risks in acupuncture side effects and precautions. Real-versus-sham comparisons matter because NCCIH notes that some trials found real and sham acupuncture equally effective, which suggests a placebo effect. [3] See placebo, sham controls and blinding. Tai chi and qigong for balance are covered in Tai Chi.
Vascular dementia and Alzheimer's disease
- Chinese herbal medicine for vascular dementia (Cochrane, 2018). 47 studies (3,581 people), all in China, small (26 to 240 participants), median length 12 weeks, with poor reporting and methods, including missing blinding and incomplete reporting of adverse events. Seven products showed potentially large benefits, and three (NaoXinTong, NaoMaiTai, TongXinLuo) had the strongest evidence for further research; two had a 5% or higher increased risk of adverse events versus no treatment in poor-quality evidence. The authors called the evidence of benefit and harm moderate to very low quality. [5] Label: insufficient evidence.
- Ginkgo (Cochrane, 2026). 82 studies (10,613 people). In mild cognitive impairment ginkgo probably has little or no effect on global status, cognition or daily living at six months; in dementia there may be small to moderate benefits at six months, with low-certainty evidence and probably no difference in adverse events. [6] Label: mixed. See Ginkgo in Chinese medicine.
- Huperzine A (Cochrane, 2008). Six trials (454 people) with mostly poor quality; the authors said there was inadequate evidence to recommend its use. [7] See Huperzia and huperzine A. Label: insufficient evidence.
Where evidence is missing
Proper evidence not found for TCM preventing a stroke, reversing dementia or replacing stroke prevention medicines and rehabilitation. I searched PubMed for Cochrane reviews and systematic reviews of Chinese herbs, acupuncture, ginkgo and huperzine A in stroke and dementia. For wider memory concerns, see forgetfulness and memory loss and mild cognitive impairment and dementia.Frequently asked questions
Can acupuncture help recovery after a stroke?
A Cochrane review found possible benefits against no acupuncture but no difference versus sham acupuncture in two trials, and said evidence was inadequate for routine use. [2]
Do Chinese herbs prevent dementia?
No source reviewed shows prevention. Cochrane reviews of herbs focused on treatment in people who already had dementia and found low-quality evidence. [5]
Does ginkgo help dementia?
A 2026 Cochrane review found small to moderate possible benefits at six months in dementia (low certainty) and little or no effect in mild cognitive impairment. [6]
Is huperzine A recommended for Alzheimer's disease?
The Cochrane review said evidence was inadequate to recommend it. [7]
What are the signs of a stroke?
Face weakness, arm weakness and speech problems; call emergency services immediately. [1]

Safety
- If you take medicines after a stroke, such as blood thinners, ask a pharmacist before adding any herb. See Chinese herbs with prescription medicines.
- NCCIH reports Chinese herbal products with undeclared drugs, heavy metals, pesticides or wrong herbs. [3]
- Vascular dementia trials had incomplete adverse-event reporting, so "no harm reported" does not mean "no harm". [5]
