Asparagus Cochinchinensis Extract
Also known as: Asparagus cochinchinensis (Lour.) Merr., Chinese asparagus, Cochinchinese asparagus, Asparagus cochinchinensis
Overview
Asparagus cochinchinensis extract is derived from the roots of the plant, traditionally utilized in East Asian medicine for various conditions, including respiratory, digestive, and inflammatory issues. This herbal extract is rich in bioactive steroidal saponins, particularly methyl protodioscin, which are considered its primary pharmacologically active compounds. It is primarily investigated for its anti-inflammatory, antioxidant, and neuroprotective properties. While promising, research on this extract is still emerging, with a body of in vitro and in vivo studies, but a notable absence of high-quality human clinical trials. The current evidence base is moderate, predominantly preclinical, with findings from animal models, and no large-scale randomized controlled trials or meta-analyses in humans.
Benefits
Asparagus cochinchinensis extract demonstrates several potential benefits, primarily supported by preclinical research. Its anti-inflammatory effects are significant, with studies showing that the extract and its constituent methyl protodioscin inhibit proinflammatory cytokines (IL-6, IL-8, TNF-α) in lung epithelial cells and reduce inflammatory cell infiltration in mouse models of acute lung injury, suggesting potential for airway inflammatory disorders. Furthermore, it has shown antidepressant-like effects in ovariectomized rat models, ameliorating depression-like behaviors, reducing serum corticosterone and inflammatory cytokines, and restoring brain-derived neurotrophic factor (BDNF) and TrkB receptor expression, indicating neuroprotective and antidepressant potential. For skin inflammation, ethyl acetate extracts have reduced IgE levels, mast cell infiltration, and inflammatory mediators in mouse models. The extract also exhibits anticancer potential, with network pharmacology and experimental validation suggesting inhibition of colorectal cancer cell proliferation and induction of apoptosis via pathways like PI3K/AKT/mTOR in vitro and in xenograft models. Some animal studies also suggest metabolic benefits, such as reduced weight gain and improved lipid profiles in high-fat diet models, though human data are currently lacking.
How it works
The mechanism of action for Asparagus cochinchinensis extract involves several biological pathways. Its anti-inflammatory activity is primarily mediated by the inhibition of the c-Jun N-terminal kinase (JNK) and c-Jun activation pathway, which leads to the downregulation of proinflammatory cytokines. Neuroprotective effects are linked to the modulation of the BDNF-TrkB signaling pathway, crucial for neuronal survival and plasticity. The extract's anticancer effects are associated with the induction of cell cycle arrest (G0/G1 phase) and apoptosis, potentially through the modulation of multiple signaling pathways, including PI3K/AKT/mTOR and MAPK pathways. Additionally, the extract suppresses nitric oxide (NO) production, COX-2 expression, reactive oxygen species (ROS), and various inflammatory cytokines in immune cells, contributing to its overall anti-inflammatory and antioxidant properties.
Side effects
Comprehensive human safety data for Asparagus cochinchinensis extract are currently unavailable, as no significant human clinical trials or randomized controlled trials have been identified. Animal studies and in vitro experiments have not reported significant toxicity at the tested doses. Consequently, there are no commonly or rarely documented side effects in the reviewed literature. Due to the lack of clinical data, potential drug interactions and contraindications remain uncharacterized. Therefore, caution is strongly advised when considering its use, as the safety profile observed in animal models cannot be directly extrapolated to humans without further rigorous clinical investigation. Individuals should consult with a healthcare professional before considering this supplement.
Dosage
Currently, there are no established human dosing guidelines for Asparagus cochinchinensis extract due to the absence of clinical trials. Animal studies have utilized oral doses ranging from 100 to 2000 mg/kg, depending on the specific animal model and the preparation of the extract. The bioavailability and absorption characteristics in humans are not well-characterized. Therefore, defining effective and safe human doses requires further extensive research. Without human clinical data, any self-administration is not recommended, and individuals should await further scientific validation and professional guidance before considering its use.
FAQs
Is Asparagus cochinchinensis extract effective for respiratory inflammation?
Preclinical evidence from animal models supports its anti-inflammatory effects in airway inflammation, but human clinical trials are currently lacking to confirm efficacy.
Can it be used for depression?
Animal models suggest antidepressant-like effects by modulating BDNF-TrkB pathways, but clinical validation in humans is needed before it can be recommended for depression.
Is Asparagus cochinchinensis extract safe?
Animal studies show no toxicity at tested doses, but human safety data are insufficient, and comprehensive safety profiles are yet to be established.
How quickly do benefits appear?
In animal studies, effects typically appear after weeks of treatment; however, the timeline for potential benefits in humans is currently unknown.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC4562339/ – This study investigated the anti-inflammatory effects of a 70% ethanol root extract of Asparagus cochinchinensis and its constituent methyl protodioscin. It found that both inhibited IL-6, IL-8, and TNF-α in lung epithelial cells and reduced inflammatory cell infiltration in LPS-induced acute lung injury in mice, suggesting potential for airway inflammatory disorders. The study used doses of 100–400 mg/kg for the extract and 30–60 mg/kg for methyl protodioscin, with statistical significance confirmed by ANOVA.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC7590795/ – This research explored the antidepressant-like effects of Asparagus cochinchinensis extract in ovariectomized rats subjected to chronic mild stress. Treatment with the extract (1000 or 2000 mg/kg) reversed depression-like behaviors, reduced elevated inflammatory markers, and restored BDNF-TrkB signaling, indicating neuroprotective and antidepressant potential. The study had an adequate sample size and reported statistical significance, though it was limited to an animal model.
