Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common form of dementia in the elderly. It is marked by persistent memory loss, declining cognitive function, behavioral and psychological abnormalities, and eventually complete loss of self-care ability. With an insidious onset and continuous deterioration, its exact etiology remains unclear, widely believed to result from a combination of genetics, environment, and lifestyle.

Epidemiological data show that among people aged 65 and above in China, the prevalence of dementia is 5.1%, with 3.2% attributed to AD. As global aging accelerates, the socioeconomic and care burden of AD is growing rapidly, bringing huge challenges to patients and families. Modern medicine classifies AD into three stages: preclinical AD, mild cognitive impairment (MCI), and dementia. Current treatments are limited: most drugs only relieve symptoms or slow progression; long-term use may cause side effects or drug resistance; newly launched targeted therapies work only for mild cases and are costly, making them inaccessible to many patients.

Traditional Chinese Medicine (TCM) offers a unique, holistic, multi-target strategy for AD prevention and management, complementing single-target Western approaches. TCM holds that AD is rooted in the brain, closely linked to kidney deficiency, and correlated with liver and spleen dysfunction-an overall systemic imbalance rather than a local brain lesion alone. This article integrates TCM understanding of AD with modern scientific evidence, and highlights Cistanche Tubulosa extract as a promising natural ingredient to support cognitive health in AD.

 

TCM Understanding of Alzheimer's Disease

TCM has no exact term "Alzheimer's disease", but categorizes its progressive symptoms into Forgetfulness, Dementia, and Mania-Depressive Syndrome according to disease stages.

1. Forgetfulness (Early Stage: Preclinical & MCI)

This stage corresponds to early memory decline. TCM attributes it mainly to kidney essence deficiency and insufficient marrow sea. The kidney stores essence, which generates marrow to nourish the brain. When kidney essence declines, the brain loses nourishment, leading to forgetfulness, brain dizziness, tinnitus, and soreness of the waist and knees-classic signs matching early AD symptoms.

2. Dementia (Middle Stage)

As AD advances, cognitive and daily function deteriorate markedly. TCM identifies phlegm turbidity and blood stasis blocking the brain orifices, worsening the foundational kidney deficiency. Spleen weakness produces phlegm; impaired circulation leads to blood stasis. Both obstruct brain clarity, causing severe confusion, language problems, and behavioral disorders.

3. Mania-Depressive Syndrome (Advanced Stage)

In late‑stage AD, severe psychiatric and behavioral disturbances dominate. TCM views this as a mixed deficiency‑excess pattern: deep-seated kidney deficiency, phlegm stasis, plus liver depression transforming into fire, and phlegm‑fire disturbing the mind. Patients show apathy, agitation, delusions, hallucinations, and total loss of self-care ability.

Core TCM Pathogenesis of AD

TCM defines AD as a root deficiency with branch excess disorder:

Root deficiency: Kidney essence depletion, spleen weakness, qi‑blood insufficiency (the foundational causes).

Branch excess: Phlegm clouding orifices, blood stasis blocking collaterals, heat disturbing the mind (the pathological manifestations).

Key pathogenic factors:

Aging: Kidney essence naturally declines with age, failing to nourish the brain.

Chronic illness: Long-term hypertension, diabetes, or heart disease foster phlegm and stasis.

Emotional stress: Chronic anxiety or depression disrupts qi flow and triggers fire.

Constitution: Inherited weakness increases vulnerability, similar to genetic risk in Western medicine.

 

Cistanche Tubulosa: Natural Support for AD Cognitive Function

Why Cistanche Tubulosa?

Cistanche Tubulosa (desert ginseng) is a premium TCM herb historically used to tonify kidney essence, benefit essence, and nourish marrow-directly targeting the core pathogenesis of AD. Modern research confirms its neuroprotective and cognition-enhancing effects, making it ideal for AD-support products.

Scientifically Validated Efficacy of Cistanche Tubulosa for AD

Modern research shows that the active substances in Cistanche can enhance the activity of antioxidant enzymes in brain tissue, strengthen the antioxidant capacity of brain cells, and reduce nerve damage caused by neuronal apoptosis and calcium accumulation. They also protect nerve receptors and regulate neurotransmission, thereby improving learning, memory and cognitive function.

To a certain extent, it can delay cerebral cortex atrophy and widening of cerebral sulci, reduce hippocampal lesions and intracerebral senile plaque deposition, and alleviate cognitive decline. It exhibits potential protective and ameliorative effects on Parkinson's disease and Alzheimer's disease.

These actions align perfectly with TCM's goal to tonify kidney, nourish marrow, resolve phlegm, and unblock collaterals-addressing both root and branch of AD.

Integrated TCM‑Modern Approach for AD

TCM treatment follows tonify deficiency and eliminate excess:

Tonify kidney essence: Our Cistanche Tubulosa extract directly nourishes kidney and marrow, supporting brain structure and function.

Strengthen spleen and resolve phlegm: Reduces pathological phlegm that clouds brain orifices.

Promote blood circulation and unblock collaterals: Improves cerebral perfusion and reduces oxidative stress.

Clear heat and calm the mind: Eases psychiatric symptoms in advanced AD.

Early intervention is critical. Starting at the Forgetfulness (MCI) stage can effectively slow cognitive decline, preserve daily function, and delay progression to severe dementia.
