Does TCM have a concept of the brain?

Yes and no. TCM recognizes the brain as an organ — the *Huangdi Neijing* calls it the 'Sea of Marrow' (脑为髓海) and notes that 'when the sea of marrow is insufficient, there is dizziness, tinnitus, and weakness of the legs' (髓海不足，则脑转耳鸣，胫酸眩冒) [^1]. But TCM does not assign cognitive function solely to the brain the way Western medicine does. Instead, it distributes mental functions across the five Zang organs: the Heart houses the spirit (Shen), the Spleen governs thinking (Yi), the Liver manages planning (Hun), the Lungs handle organization (Po), and the Kidneys store willpower (Zhi). Memory specifically depends on Kidney essence (which produces marrow to fill the brain) and Spleen Qi (which generates enough Qi and blood to nourish the brain).

Are there TCM herbs that actually improve memory?

Several TCM herbs have been studied for cognitive effects. Ginseng (人参) has the strongest evidence base — a 2018 Cochrane review found moderate evidence that Panax ginseng improved some aspects of cognitive performance [^2]. Ginkgo biloba (银杏, though more commonly associated with Western herbalism, it has a long history in TCM) has been extensively studied with mixed but generally positive results for age-related cognitive decline. In TCM practice, the most commonly prescribed herbs for memory are Ren Shen (ginseng), Yuan Zhi (Polygala), Shi Chang Pu (Acorus), and Wu Wei Zi (Schisandra). However, TCM always prescribes these in combinations based on pattern differentiation — there is no single 'memory herb' taken in isolation.

TCM and Memory (记忆力): Why Chinese Medicine Says Brain Health Starts in the Spleen and Kidneys

A Different Way of Thinking About Thinking

Western medicine locates memory in the hippocampus, concentration in the prefrontal cortex, and calls the whole system “cognitive function.” It is precise, measurable, andmaps neatly onto brain scans.

TCM takes a stranger but arguably more holistic approach. Memory and cognition are not owned by any single organ. They emerge from a collaboration:

Kidneys produce essence (精), which generates marrow, which fills the brain. The Ling Shu states this directly: “The brain is the sea of marrow” (脑为髓海) [^1]. No Kidney essence, no brain nourishment, no memory.
Spleen transforms food into Qi and blood. If the Spleen is weak, not enough Qi reaches the head. You feel “brain fog” — that muzzy, sluggish feeling after a heavy meal or during a stomach bug? That is Spleen Qi failing to rise clearly to the brain.
Heart houses the Shen (spirit, consciousness). When Heart blood is deficient, the spirit has no home — thoughts scatter, focus is impossible, and memory fragments.
Liver ensures smooth Qi flow. Stagnation from stress or frustration creates a kind of mental traffic jam — you cannot think clearly because the energy is stuck.

The Bencao Bei Yao (《本草备要》, 1694) by Wang Ang summarizes this beautifully: “Memory depends on the Shen, the Shen depends on the Heart, and the Heart depends on Qi and Blood. If Qi and Blood are insufficient, the Shen has no nourishment and memory fails” (记性在心，心主血，血虚则神昏而善忘) [^3].

Patterns Behind Poor Memory

Kidney Essence Deficiency (肾精不足)

This is the pattern most people recognize as “aging brain.”

Gradual memory decline over years
Difficulty learning new things
Accompanied by lower back pain, tinnitus, frequent urination
Gray hair, dry eyes
The Suwen connects this directly to aging: “At age 48, the Yang Ming channels decline… the face begins to wither and the hair turns white” (阳明脉衰，面始焦，发始堕) [^4]

Dietary approach: Black foods — black sesame, black beans, walnuts, sea cucumber, bone broth. These are traditional Kidney-nourishing foods.

Key herbs: He Shou Wu, Gu Sui Bu, Rou Cong Rong, Shu Di Huang

Spleen Qi Deficiency (脾气虚)

The “brain fog” pattern.

Heavy feeling in the head, difficulty concentrating after meals
Poor appetite, easy fullness
Fatigue that worsens with mental effort
Loose stools

This pattern is increasingly common in office workers who eat quickly at their desks and never properly digest. The Spleen literally cannot keep up with demand.

Dietary approach: Shan Yao (Chinese yam), Bai Zhu, lotus seeds, millet porridge. Warm, easily digestible foods eaten slowly.

Key herbs: Huang Qi, Dang Shen, Bai Zhu, Fu Ling

Heart Blood Deficiency (心血虚)

The “scattered mind” pattern.

Difficulty falling asleep because thoughts race
Waking frequently, dreams are vivid and exhausting
Anxiety about forgetting things (which makes remembering harder)
Pale complexion, palpitations

Dietary approach: Red dates, longan berries, lotus seeds, lily bulb.

Key herbs: Suan Zao Ren, Bai Zi Ren, Yuan Zhi, Dang Gui

Herbs With Real Evidence

I want to be honest about what the research supports and what it does not.

Ginseng (人参 / Ren Shen)

This has the strongest evidence. A systematic review and meta-analysis by Lee & Son (2018) in the Cochrane Database of Systematic Reviews looked at 16 randomized controlled trials and found that Panax ginseng showed “some improvement in aspects of cognitive performance, behavior, and quality of life” compared to placebo [^2]. The effect was modest but consistent.

Ginkgo Biloba (银杏叶)

Strictly speaking, Ginkgo is more prominent in the Western herbal tradition, but it appears in Chinese medicine as well (the seed, Bai Guo, is used in TCM for asthma; the leaf came into wider use later). A large 2009 trial (the EGb 761 study) published in JAMA found no effect on preventing dementia in healthy older adults [^5], but subsequent re-analyses and smaller trials have suggested benefits for patients who already have cognitive decline.

Yuan Zhi (远志 / Polygala Root)

This is the TCM herb most specifically associated with memory. Its name literally means “far-reaching aspiration” — the ancient naming suggests it was valued for mental clarity. A 2016 study in Neuropharmacology demonstrated that polygalasaponins (active compounds from Yuan Zhi) improved spatial memory in mice and increased expression of BDNF (brain-derived neurotrophic factor) [^6]. BDNF is the same protein that exercise stimulates, and it is crucial for memory formation.

Shi Chang Pu (石菖蒲 / Acorus)

Often paired with Yuan Zhi in formulas. The Shennong Bencao Jing lists it for “joyous forgetfulness” — a term that puzzled translators until it was understood to mean a scattered, unfocused state of mind. Modern pharmacological studies have identified β-asarone as the key compound, showing neuroprotective effects in laboratory studies [^7].

The Famous Memory Formula

Kai Xin San (开心散), recorded in the Qian Jin Yao Fang (《千金要方》, 652 CE) by Sun Simiao:

| Herb | Dose | Role | |------|------|------| | Yuan Zhi (远志) | 6g | Opens the orifices, calms the spirit | | Shi Chang Pu (石菖蒲) | 6g | Opens the mind, dispels phlegm | | Fu Ling (茯苓) | 15g | Strengthens Spleen, calms Heart | | Ren Shen (人参) | 6g | Tonifies Qi, generates fluids | | (Sometimes Long Yan Rou added) | 10g | Nourishes Heart blood |

Sun Simiao prescribed this for “forgetfulness and inability to concentrate” (好忘) [^8]. What I find interesting is the logic: Yuan Zhi and Shi Chang Pu are the “opening” pair (they clear phlegm and mental fog), while Ren Shen and Fu Ling are the “nourishing” pair (they provide the Qi that the brain runs on). Clear the blockages, then feed the organ.

Practical Advice

Rather than listing a generic set of recommendations, here is what I would suggest based on TCM patterns:

If your memory issues come with lower back pain and tinnitus: Focus on Kidney nourishment. Eat black sesame paste daily, take bone broth, consider He Shou Wu (consult a practitioner). Go to bed before 11 PM.

If your memory issues come with brain fog after meals: Focus on Spleen strengthening. Eat warm, cooked meals. Avoid raw food and cold drinks. Millet porridge with Chinese yam for breakfast is a traditional recommendation. Huang Qi tea can help.

If your memory issues come with anxiety and insomnia: Focus on Heart blood. Longan berry and red date tea before bed. Suan Zao Ren Tang (酸枣仁汤) is the classic formula — but get a proper TCM consultation first.

If your memory issues come with stress and frustration: Focus on moving Liver Qi. Exercise, deep breathing, reduce alcohol. Chai Hu + Bai Shao is the basic pair for this pattern.

A Final Note on Expectations

TCM approaches to memory are not quick fixes. They work by addressing the underlying organ patterns that support cognitive function. Expect weeks to months of consistent dietary and herbal work before noticing changes. If memory loss is sudden or rapidly progressive, see a neurologist — that is not a TCM problem, that is a medical emergency.
