Curculigo Extract
Also known as: Curculigo orchioides Gaertn., Golden Eye-Grass, Xian Mao, Curculigo orchioides
Overview
Curculigo orchioides, also known as Golden Eye-Grass or Xian Mao, is a plant used in traditional medicine, particularly in Asian countries. It is valued for its potential health benefits, including cognitive enhancement, immune support, and potential applications in managing conditions like diabetes. The primary bioactive compound in Curculigo orchioides is curculigoside, a phenolic glycoside known for its antioxidant and anti-inflammatory properties. While research on Curculigo orchioides extract is growing, it is important to note that systematic reviews and meta-analyses, which provide more robust evidence, are still lacking. The plant is typically used in extract form, leveraging its concentrated bioactive compounds. Further research is needed to fully understand its mechanisms and therapeutic potential.
Benefits
Curculigoside from Curculigo orchioides has demonstrated potential cognitive benefits in animal studies. Specifically, it has been shown to improve learning and memory in aged rats, possibly by inhibiting acetylcholinesterase activity and reducing BACE1 expression, both of which are relevant to Alzheimer's disease pathology. Another potential benefit observed in animal studies is the protection against heat stress-induced reproductive dysfunction in male mice, where the extract helped maintain testosterone levels and spermatogenesis. These benefits suggest potential applications for older adults experiencing cognitive decline and individuals exposed to heat stress, although human studies are needed to confirm these effects.
How it works
Curculigoside, the primary bioactive compound in Curculigo orchioides, is believed to exert its effects through several mechanisms. It may inhibit acetylcholinesterase, an enzyme that breaks down acetylcholine, thereby increasing acetylcholine levels in the brain and potentially enhancing cognitive function. Additionally, it can reduce the expression of BACE1, an enzyme involved in the formation of amyloid plaques associated with Alzheimer's disease. The extract also exhibits antioxidant and anti-inflammatory properties, which may contribute to its overall health benefits by protecting cells from damage and reducing inflammation in the body.
Side effects
While Curculigo orchioides is generally considered safe based on its traditional use, comprehensive safety studies are limited. Common side effects are not well-documented, and information on potential drug interactions and contraindications is lacking. Due to the limited data, caution is advised for pregnant or breastfeeding women. More research is needed to fully understand the safety profile of Curculigo orchioides extract, including potential adverse effects, interactions with medications, and contraindications for specific populations. Individuals considering using this supplement should consult with a healthcare provider to assess potential risks and benefits.
Dosage
Currently, there is no established minimum effective dose, optimal dosage range, or maximum safe dose for Curculigo orchioides in humans. Animal studies have used doses like 20-40 mg/kg/day of curculigoside. However, these dosages cannot be directly translated to human use. As a result, specific dosage recommendations are not available. It is typically used as an extract in traditional medicine. Given the lack of human data, it is crucial to consult with a healthcare provider before using Curculigo orchioides to determine an appropriate and safe dosage, if any.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC6268871/ – This study on aged rats demonstrated that curculigoside improved learning and memory by inhibiting acetylcholinesterase and reducing BACE1 expression. The findings suggest a potential cognitive benefit, but the study is limited by its animal model and lack of human data. The study lasted 14 days and showed significant improvement in cognitive function in the rats.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10136419/ – This animal study showed that Curculigo orchioides extract protected against heat stress-induced reproductive dysfunction in male mice by maintaining testosterone levels and spermatogenesis. The study involved 48 mice over 6 weeks and found protective effects on testicular function. However, the results are limited by the animal model and require confirmation in human studies.
- https://www.mdpi.com/2073-4409/13/23/2028 – This study on Curculigo capitulata suggests potential benefits for osteoporosis by promoting osteoblast proliferation. The in vitro and animal study showed that the extract promotes osteoblast activity. However, the study uses a different species and is not directly applicable to Curculigo orchioides.
- https://www.mdpi.com/1467-3045/45/4/212/review_report – This is a review report, but it does not provide specific research findings related to Curculigo orchioides. It is a general overview of the topic.
