It improves mood, mental performance, cognitive skills, stamina, and physical endurance. It stimulates the mind and reduces mental fatigue and mental stress. It also improves lung function, so improves the lungs health and eases breathing.
It is also beneficial for women because it reduces menstrual discomfort and helps to manage menopausal symptoms. Ginseng Root is used in form of white ginseng or red ginseng for the treatment of Alzheimer’s disease, fatigue, low immunity, depression, anxiety, and cystic fibrosis. It is also likely to be beneficial in anemia, diabetes, gastritis, hangover, chronic bronchitis, flu, and delirium in high-grade fever.

The roots of Panax Ginseng have therapeutic value. It is available in two forms – White ginseng and red ginseng discussed under types of Panax ginseng below. Red ginseng is commonly used for getting therapeutic benefits.
Fresh roots are sliced and advised to eat raw. The dried roots are used in form of powder. Dried roots are also used to make a decoction. The standardized extracts derived from the roots are used to make capsules or tablets and added in several health supplements. Dried roots are also used to make ginseng tea and ginseng mother tincture (alcoholic extract). Each preparation has different dosage, which will be discussed later in this article.
Types of Panax Ginseng
In the market, there are mainly two types of Panax Ginseng (True Ginseng) available. However, both come from the same plant, but have a difference in processing and preserving methods.
- White Ginseng
- Red Ginseng
The roots of Ginseng are peeled off and dried in the air and in the sun. The moisture content in white ginseng is below 12% and its color is yellowish white. There are some enzymes present in the roots that decrease the therapeutic value of the white ginseng by breaking down the active constituents during the processing.
Main Bioactive Constituents in White Ginseng
- Ginsenoside Rb1
- Ginsenoside Ro
- Ginsenoside Re
Korean Red Ginseng
The product obtained by steaming and then sun-drying the roots of panax ginseng without peeling off is called Korean Red Ginseng. In this process, heat (steaming) involves that changes the bioactive constituents in the roots and increases the shelf life. Its color is reddish brown. The steaming process prevents the deterioration of active constituents and likely to alter the phytochemistry (biochemical composition) in the roots. This process improves the therapeutic value of the ginseng.
Main Bioactive Constituents in Red Ginseng
- Ginsenoside Rb3
- Ginsenoside Rg3
Fermented Red Ginseng
The steamed and dried Red Ginseng is further fermented. The fermentation process improves its efficacy and safety. It further improves the bioavailability of Ginsenosides in the human body. (1)

Stress, Anxiety and Depression
Ginseng is an adaptogen and antidepressant that reduces stress and it is helpful for treating anxiety disorders and depression. It improves blood circulation to the brain, which helps to reduce the effects of mental stress. It reduces aggression and improves social behaviour. Ginsenosides, main components in the ginseng, exert anti-stress and anti-depressive effects. Acidic polysaccharide content also acts as antidepressant. (2, 3)
Acetate fermented Korean Red ginseng is more effective for stress disorders, anxiety disorders and depression because it has more potent antidepressant effects than other forms of the ginseng. (4)
Ginseng might alter genetic transcription of tyrosine hydroxylase (TH) and dopamine β-hydroxylase (DBH). It attenuates the increased level of TH and DBH that elevate in stress and restores the natural level of neurotransmitters. This process helps to reduce the mental stress. (5)
The anxiolytic effects of the Ginseng are comparable with diazepam. (6)
