Ginkgo vs Ginseng vs Bacopa: Memory Herbs Compared
Ginkgo, Asian ginseng and bacopa are all sold for memory. Here is what trials and reviews found for each, where they differ, and the safety points to know.

Safety first. Natural products can cause side effects and interact with medicines. Read herb safety and interactions before you use anything on this page.
Safety first. Ginkgo may raise bleeding risk with blood thinners such as warfarin, and Asian ginseng may interfere with blood clotting and lower blood sugar. [1][2] Tell your pharmacist or clinician, and your surgical team before any procedure. See how herbs and medicines interact.
The question
People often ask which of these three "memory herbs" is better. We found no trial in which the three were tested against each other. Proper evidence not found for a head-to-head winner (we searched PubMed for trials naming ginkgo, ginseng and bacopa together). What can be compared is what each one has been tested for, on its own, with its own extract.What each plant is
- Ginkgo (Ginkgo biloba, leaf extract): a tree with a long history in Chinese medicine. Leaf extract is the most common form today. [1][3]
- Asian ginseng (Panax ginseng, root): used in traditional Chinese medicine and described as an adaptogen. It is not the same plant as Siberian ginseng. [2] See the Asian ginseng profile in Adaptogens.
- Bacopa (Bacopa monnieri, leaf extract; also called brahmi): used for centuries in Ayurvedic medicine. [4][5] See the bacopa profile.
These are traditional uses. They are not proof of benefit.
What research found, side by side
| Question | Ginkgo | Asian ginseng | Bacopa |
|---|---|---|---|
| Dementia or mild memory loss (cognitive impairment) | Cochrane review of 82 studies: little or no effect in mild cognitive impairment; small to moderate possible benefit in dementia. [6] Mixed | Cochrane review: no high quality evidence in dementia. [7] Insufficient evidence | Proper evidence not found for dementia in the sources we read (searched PubMed); the meta-analysis authors said trials in dementia are still needed [5] |
| Healthy adults | NCCIH: uncertain whether it changes thinking in healthy people, and much research is low quality. [1] Insufficient evidence | Cochrane: lack of convincing evidence in healthy people. [7] Insufficient evidence | A meta-analysis of 9 trials (518 people) of standardized extract taken 12 weeks or longer suggested faster attention, but the authors said a larger trial was needed. [5] Promising but limited |
| Size of the research | Includes large trials, such as a study of over 3,000 older adults followed for a median of 6 years [1] | Most trials small, under 200 people and under 3 months [2] | Nine trials in the meta-analysis [5] |
NCCIH also notes that any memory benefit seen with Asian ginseng seemed to depend on ginkgo being added. [2] Products and extracts differ, so one trial does not transfer to another product.
No universal winner
Each has a different evidence picture and a different set of cautions. Memory changes can have treatable causes, so see a clinician for new or worsening forgetfulness. Related reading: herbs for memory and focus, the ginkgo profile, and quality testing.Frequently asked questions
Which is best for memory: ginkgo, ginseng or bacopa?
We found no trial comparing all three, so no one can be named. Each has been tested separately with mixed or limited results. [6][7][5]
Does ginkgo prevent dementia?
NCCIH says ginkgo has not been shown to prevent or slow dementia; in large studies of older adults, ginkgo extract did not reduce dementia risk. [1]
Can I take these with blood thinners?
Ginkgo and Asian ginseng both have clotting or bleeding warnings. Ask a pharmacist before combining. [1][2]
Is Asian ginseng the same as Siberian ginseng?
Asian ginseng is one of several types of ginseng. [2] Eleuthero ("Siberian ginseng") is covered separately; see ginseng vs eleuthero.
Are they safe in pregnancy?
Ginkgo may be unsafe in pregnancy, some studies suggest the same for Asian ginseng, and bacopa needs more research. Ask your clinician. [1][2][9]

Safety differences
| Point | Ginkgo | Asian ginseng | Bacopa |
|---|---|---|---|
| Bleeding or clotting | May increase bleeding with anticoagulants. [1] Case reports of bleeding with warfarin or aspirin. [8] | May interfere with blood clotting. [2] | Not described in the sources we read |
| Other medicines | NCCIH says it may also interact with other drugs. [1] | Might lower blood sugar; case report of mania with an antidepressant (phenelzine). [2][8] | A 2025 review says some medicine interactions and thyroid conditions deserve care. [9] |
| Liver | NIH LiverTox: not implicated in liver injury. [10] | NCCIH lists liver damage as an uncommon reported effect, along with severe rash and allergic reactions. [2] | LiverTox: not linked to clinically apparent liver injury. [4] |
| Common side effects | Dizziness, stomach upset, headache [1] | Insomnia [2] | Reviewed as generally non-toxic. [9] |
| Pregnancy | May be unsafe. [1] | Some studies suggest it may be unsafe. [2] | More research needed, especially in pregnancy and breastfeeding. [9] |
Fresh ginkgo seeds are toxic, and serious effects have been reported with roasted seeds and the crude plant. [1] Leaf extract is the most commonly used form. [1]
