Research progress on vesicles from Chinese medicinal herbs.

Area of Science:

• Nanomedicine
• Pharmacology
• Biotechnology

Background:

• Vesicles derived from Chinese medicinal herbs (VCMH) are nano-vesicular entities with inherent biological activities and targeting capabilities.
• VCMHs exhibit distinct advantages over animal-derived vesicles, including enhanced stability, specificity, and safety.
• Their composition and function are intrinsically linked to the parent herb, offering a unique source of therapeutic agents.

Approach:

• Review of various extraction and isolation techniques for VCMH, highlighting the benefits and drawbacks of each method.
• Systematic examination and evaluation of VCMH characteristics, including morphology, size (10-300 nm), and composition (lipids, proteins, nucleic acids).
• Assessment of VCMH biological activities, such as anti-inflammatory, antioxidant, anti-tumor, and anti-fibrotic effects.

Key Points:

• VCMHs possess excellent biocompatibility and low toxicity.
• They function as effective drug carriers, enhancing drug delivery efficiency and stability both in vitro and in vivo.
• Modification of VCMH structure can yield more precise and stable drug delivery systems.

Conclusions:

• VCMHs represent a promising platform for novel drug delivery and therapeutic applications.
• Further research into extraction, purification, and modification techniques is crucial for optimizing VCMH utilization.
• VCMHs offer a sustainable and potent source for developing new active substances and targeted drug carriers.
