THERAPEUTIC ACTIONS

I. IMMUNE SYSTEM

1. Strongly tonifies Yuan Qi – enhances resistance
   Traditionally used to strongly tonify original qi, support the body’s defensive qi, and help the body resist common colds, excessive spontaneous sweating, fatigue, weakness, dizziness, and lightheadedness.
2. General tonic – increases physical endurance
   • Enhances adaptation to environmental and physical stress
   • Helps athletes improve stamina and endurance
   • Does not stimulate like caffeine and is non-addictive
   • Increases oxygen utilization, raises VO₂ max
   • Optimizes glucose metabolism during exercise
3. Bidirectional immunomodulation
   • Regulates immune function in both directions:
     • Enhances immunity when the body is weakened
     • Reduces excessive inflammation when the immune response is overactive
   • Exhibits antiviral activity: increases interferon, inhibits influenza virus
   • Used in syndromes of combined yin and yang deficiency.
4. Promotes longevity – activates hidden potential
   Long-term, appropriate use can help strengthen the body, support healthy aging, and slow functional decline.
5. Qi collapse (qi desertion) 
   Used in emergencies in Traditional Chinese Medicine for extreme deficiency states characterized by:
   • Profound exhaustion, very weak voice, speaking in a low, faint tone
   • Cold clammy sweat, cold limbs
   • Shallow, labored breathing, gasping
   • Pale or ashen-gray complexion
   • Dull or clouded consciousness, feeling close to collapse
     This pattern is considered a critical condition approaching “collapse syndrome” in TCM.

II. DIGESTIVE SYSTEM – SPLEEN & STOMACH – METABOLISM

1. Tonifies the Spleen – improves digestion and absorption
   Used for poor appetite, Spleen–Stomach deficiency, reluctance to eat, cold-deficient Stomach, nausea with phlegm, or a tendency to vomit.
2. Generates body fluids – relieves thirst – supports blood sugar balance
   • Helps relieve excessive thirst and is used as an adjunct in “wasting-thirst” (diabetes) patterns
   • Promotes generation of body fluids
   • May help lower blood glucose levels
3. Regulates gut microbiome
   Ginsenosides help modulate intestinal microbiota:
   • Increases beneficial bacteria
   • Reduces intestinal inflammation
   • Protects the intestinal mucosa
4. Liver protection & metabolic support
   • Helps protect the liver and enhance its detoxification function
   • May reduce hepatic inflammation
   • Supports improvement in non-alcoholic fatty liver disease (NAFLD)
   • Helps reduce accumulation of triglycerides (modern research)

III. RESPIRATORY SYSTEM – LUNG

1. Tonifies Lung qi – supports respiratory function
   Used to:
   • Support treatment of tracheitis, bronchitis, asthma, pulmonary edema
   • Help clear nasal passages, relieve cough, common cold, fever, headache
2. Assists Lung qi – reduces dyspnea
   • Strengthens Lung qi, improves ventilation, reduces shortness of breath
   • Can also be used in cases of nosebleeds (epistaxis) due to qi deficiency not holding Blood.

IV. CARDIOVASCULAR SYSTEM – CIRCULATION

1. Supports deficiency of qi and blood
   Used in patterns of qi–blood deficiency with fatigue, palpitations, dizziness, and general weakness.
2. Regulates blood pressure & protects the cardiovascular system
   • Helps regulate blood pressure
   • May help prevent elevated cholesterol and atherosclerosis
   • Reduces blood lipids and plaque formation
   • Promotes vasodilation and increases nitric oxide production → natural vessel relaxation and improved endothelial function

V. ENDOCRINE SYSTEM – HORMONES – METABOLISM

1. Regulates the HPA axis – reduces stress hormones
   • Modulates the hypothalamic–pituitary–adrenal (HPA) axis
   • Helps decrease excessive cortisol
   • Supports chronic stress states and anxiety
2. Balances sex hormones & adrenal function
   • Helps regulate sex hormone balance
   • Supports menopausal symptoms
   • May naturally increase testosterone and improve libido
   • Harmonizes interaction between the pituitary gland and adrenal glands, thereby:
     • Reducing excessive ACTH stimulation of the adrenals
     • Helping prevent adrenal cortex hypertrophy due to chronic overstimulation
   • Supports balanced cortisol production, avoiding both deficiency and excess that can lead to adrenal dysfunction.

VI. NERVOUS SYSTEM

1. Calms the Shen – stabilizes the mind
   • Used to calm the spirit
   • For palpitations, fearfulness, and mental restlessness
2. Improves sleep
   Can be used as support in cases of insomnia and poor sleep quality.

   • Improves memory and concentration, “opens the mind”
   • Helps protect nerve cells
   • May reduce the risk of Alzheimer’s disease (inhibits amyloid-beta accumulation)
   • Enhances acetylcholine transmission
4. Anti-depressant & adaptogenic effects
   • Acts as an adaptogen, helping the body adapt to stress

IX. MUSCULOSKELETAL SYSTEM

• Increases muscle strength, reduces muscle fatigue
• Used in patterns of limb weakness and “four limbs lacking strength”
• Helps improve efficiency of muscular energy utilization.

X. ANTI-CANCER – ANTI-RADIATION – ANTI-INFLAMMATORY

1. Anti-tumor support
   • May inhibit growth of certain cancer cells (experimental data)
   • Traditionally used in patterns of masses and accumulations
   • Has the potential to soften and disperse certain chest masses (theoretical/TCM indication).
2. Reduces radiation damage
   • Used as adjunctive support to help reduce side effects of radiation exposure or radiotherapy.
3. Strong anti-inflammatory activity
   • Modulates NF-κB pathway
   • Reduces inflammatory mediators such as TNF-α, IL-6
   • Therefore can be used as support in many chronic inflammatory conditions.
