Codonopsis lanceolata

Codonopsis lanceolata is a perennial plant belonging to the Campanulaceae family, native to East Asia, particularly Korea, Japan, and China. It has been used in traditional medicine for various therapeutic purposes and is sometimes referred to as "bastard ginseng" or "poor man's ginseng" due to its similar properties to Panax ginseng, though at a lower cost.

Botanical Description and Origin

Codonopsis lanceolata is predominantly found in the forests of Korea and China. The medicinal part of the plant is primarily the root, which is harvested, washed, and dried in autumn for medicinal use. The plant has been used in traditional East Asian medicine for centuries.

Chemical Composition

Scientific research has identified numerous bioactive compounds in Codonopsis lanceolata, including:

• Triterpenoid saponins (including lancemaside A)
• Polyacetylenes (including lobetyolin)
• Flavonoids
• Lignans
• Steroids
• Phenylpropanoids
• Glycolipids
• Phospholipids
• Amino acids

A recent study published in January 2025 identified 27 compounds in the roots, including a previously unreported triterpenoid saponin.

Therapeutic Uses and Effects

Codonopsis lanceolata has been traditionally used to treat various conditions, including:

• Cough and bronchitis
• Inflammation
• Lung abscesses
• Milk-flow obstruction
• Inflamed boils

Modern research has demonstrated several pharmacological activities:

• Vasodilatory effects: Lancemaside A, a major compound in the plant, has shown significant time-dependent vasodilatory effects in rat aortic ring specimens.
• Metabolic regulation: Non-clinical studies suggest effectiveness in regulating fat metabolism and suppressing obesity.
• Immune system support: Used to boost the immune system and protect cancer patients against radiation treatment side effects.
• Respiratory support: Traditional use for treating asthma, cough, and bronchitis.
• Digestive health: Used for loss of appetite, chronic diarrhea, and digestive disorders.

Safety Profile

Toxicity studies indicate that Codonopsis lanceolata is generally safe:

• Acute toxicity assessment showed no influence on mortality, clinical appearance, body weight gain, or necropsy findings at doses up to 5000 mg/kg body weight.
• Subchronic oral toxicity studies revealed that doses of 1250, 2500, and 5000 mg/kg body weight/day did not cause significant toxicity to male or female rats.
• The 50% lethal dose (LD50) was determined to be greater than 5000 mg/kg.

However, like other medicinal herbs, caution is advised:

• Not recommended during pregnancy and breastfeeding due to insufficient safety data.
• May slow blood clotting, so it should be avoided before surgery and by those with bleeding disorders.
• Potential interactions with medications that slow blood clotting, diabetes medications, and certain cancer drugs like abiraterone.

Modern Applications

Beyond traditional medicine, Codonopsis lanceolata is being explored for:

• Clinical trials for improving muscle strength in adults with reduced muscle strength (sarcopenia).
• Use in health foods, cosmetics, and dietary supplements.
• Development as a natural ingredient in functional foods and beverages.

The plant continues to be studied for its potential health benefits, with recent research focusing on its chemical composition and biological activities to support its use as a health material.
