What are the morphological characteristics of this plant?
Panax notoginseng has a fleshy, spindle-shaped taproot that is typically light yellow to white in color and possesses a characteristic pungent aroma. The aerial portion consists of a perennial herbaceous structure featuring large, palmate leaves that often grow in clusters of three to five leaflets. These leaves are dark green and possess serrated margins along their edges. During the flowering stage, the plant produces small, white, star-shaped flowers arranged in umbels on a central stalk. After pollination, the plant develops small, round berries that transition from green to a bright red color when fully ripe.
What is the geographical distribution of this plant?
This plant is native to the mountainous regions of the Korean Peninsula and parts of northeastern China. It thrives primarily in temperate forest ecosystems characterized by high humidity and cool climates. Its natural habitat is typically restricted to shaded areas with well-drained, organic-rich soil found at specific elevations. Due to its specialized environmental requirements, the species is often confined to protected woodland zones. Wild populations are increasingly rare as natural habitats face pressure from human activity and climate shifts.
How is this plant cultivated?
This plant Panax notoginseng requires cultivation in shaded, well-drained mountain soils with a temperature range between 15 and 25 degrees Celsius and consistent moisture levels.
Growers typically plant the rhizomes in early spring once the frost has subsided to ensure stable root development. Because the species is sensitive to direct sunlight, farmers often use artificial shading structures to mimic the forest floor environment. Regular irrigation and careful weed management are essential to prevent competition for nutrients during the long growing period.
After several years of careful monitoring, the roots are harvested when they reach the desired medicinal potency.
What parts of this plant are used medicinally?
Panax notoginseng contains bioactive saponins and polysaccharides primarily concentrated in its fleshy taproot. This underground root is harvested and processed to extract the medicinal compounds used in traditional and modern pharmacology. While the root is the principal part used for therapeutic purposes, some studies also investigate the potential benefits of the rhizomes. The specific ginsenosides found within these root tissues are credited with supporting cardiovascular health and cognitive function. Consequently, the entire root structure is carefully cultivated to ensure a high concentration of these valuable medicinal elements.
What traditional systems uses this plant?
This plant, Panax notoginseng, has been utilized for centuries in Traditional Chinese Medicine to promote blood circulation and stop bleeding.
Practitioners historically prescribed the root to treat various ailments including bruises, swelling, and abdominal pain. It was often combined with other herbs to balance the body's internal energy and support recovery from injuries. Ancient texts frequently describe its role in managing cardiovascular issues and regulating menstrual cycles.
This long-standing medicinal history has established the species as a vital component of regional herbal practices.
What are the pharmacological activities of Panax notoginseng?
This plant has anti-inflammatory, anti-oxidant, blood circulation promoting, neuroprotective, and immunomodulatory pharmacological activities. Its bioactive compounds work to reduce systemic inflammation by inhibiting key pro-inflammatory cytokines. The high antioxidant content helps neutralize free radicals, thereby protecting cells from oxidative damage. Furthermore, the plant enhances blood circulation and supports neurological health through its potent neuroprotective properties. Finally, its immunomodulatory effects assist in regulating the body's natural immune response to maintain homeostasis.
According to a study published by "Steroids", 11 new 20(S)-protopanaxadiol type saponins were obtained from the leaves of Panax notoginseng, named as notogiensiosides NL-E1-NL-E4 (1-4), NL-F1 (5), NL-F2 (6), NL-G1 (7), NL-G2 (8), and NL-H1-NL-H3 (9-11). These compounds, including the 20(S)-PPD type saponins with aglycone (20S,24ζ)-3β,12β,20,24,25-pentahydroxy dammarane, were examined for nitric oxide inhibitory activities in LPS-stimulated RAW264.7 cells. Compounds 2-7 and 10 exerted NO inhibitory activity at 25 μM without cytotoxicity. These inhibitory activities occurred in a dose-dependent manner at 1, 10, and 25 μM. Notably, notogiensoside NL-F2 (6) possessed strong biological activity even at 1 μM.
The primary pharmacological activities of this plant are shown in the list below.
- 1. anti-inflammatory
- 2. anti-oxidant
- 3. neuroprotective
- 4. blood circulation promoting
- 5. immunomodulatory
What medicinal compounds this plant contains?
This plant contains several bioactive saponins known as ginsenosides, specifically Ginsenoside Rg1, Ginsenoside Rb1, Ginsenoside Rg3, Notoginsenoside R1, and Ginsenoside Rd. These medicinal compounds are categorized into different chemical groups based on their unique molecular structures. Ginsenoside Rg1 and Notoginsenoside R1 are often studied for their potential neuroprotective and cognitive benefits. In contrast, Ginsenoside Rb1 and Ginsenoside Rd are frequently researched for their effects on the central nervous system and metabolic regulation. Additionally, Ginsenoside Rg3 is noted for its significant role in supporting anticancer activities and immune modulation.
According to a study published by "Cells", Panax notoginseng contains Ginsenoside Rg1 (G-Rg1), which is a saponin composed of natural active ingredients. This compound is derived from the roots or stems of the plant. Its pharmacological activity against cerebral ischemia and reperfusion injury involves 4 sets of mechanisms. These include anti-oxidant activity through pathways such as Akt, Nrf2/HO-1, PPARγ/HO-1, ERK, p38, and c-Jun N-terminal kinase (JNK). Additionally, the compound acts through MAPK pathways including JN1/2 + ERK1/2 and the PI3K-Akt/mTOR, PKB/Akt, and HIF-1α/VEGF pathways.
The primary medicinal compounds of this plant are shown in the list below.
- Ginsenoside Rg1

What health conditions is this plant used for?
This plant is used for managing Alzheimer's disease, Parkinson's disease, diabetes, cardiovascular disease, and cognitive impairment. Its active ginsenosides help protect neurons from damage to improve memory and focus in patients facing cognitive impairment. Research suggests the herb may also stabilize blood sugar levels for individuals managing diabetes. Additionally, it is studied for its ability to support heart health and reduce risks associated with cardiovascular disease. These properties make it a significant subject in neuroprotective and metabolic health studies.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", Panax notoginseng saponins are used to address the brain lesions found in an Alzheimer's disease (AD) rat model. The study established these AD rat models through the intra-peritoneum injection of D-galactose combined with the injection of excitatory neurotoxin ibotenic acid into bilateral nbM. Research focused on the activity and content of synaptophyis protein in the brain to observe the protective effects of Panax notoginseng saponins. The results showed that Panax notoginseng saponins could reduce the lesion of the level of synaptophyis protein in the brain compared to the model group's rats. Ultimately, Panax notoginseng saponins play a protective role by reducing the down of the level of synaptophyis protein in the brain in this AD animal model.
The main health conditions this plant is used for are shown in the list below.
- Alzheimer's disease
