An herb is a plant or part of a plant that people take for health benefits as dietary supplements or medication. Herbal medicine may also be referred to as phytotherapy or use of botanicals. Herbal medicine interventions include a variety of substances and combinations of substances. Herbal medicine is contraindicated with some chemotherapy agents.

STUDY PURPOSE: To conduct a systematic review of the research evidence for the effects of Radix Astragali (RA)–based Chinese herbal medicine in the prevention and treatment of oxaliplatin-induced peripheral neuropathy (PN)
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: Not specified or not applicable; cannot determine if studies were in palliative care setting
APPLICATIONS: Elder care
This meta-analysis indicated that RA-based interventions may provide potential benefit for oxaliplatin-induced PN. Although this meta-analysis did not show significant heterogeneity for different trial results, it did show considerable heterogeneity in the variables, treatments, and outcome measures studied. Studies included RA-based interventions with no reliable measures of drug composition, varied drug doses, self-made drug preparations, or RA combined with herbal compositions with variation in drug delivery methods. Therefore, it is premature to interpret these results as beneficial because of the substantial limitations for reliability and validity of the study results.
It remains unclear if RA provides benefit in alleviating oxaliplatin-induced PN. Additional RCTs are required to evaluate the reliable preparations of RA to investigate its full effects isolated in simple form versus its combined effect with other herbs. The effect of RA on the antitumor activity of oxaliplatin or other chemotherapeutic agents needs further study. Large multisite RCTs are needed to further evaluate drug safety in all phases of treatment and to identify the most effective dose, delivery method, duration of treatment, and quality of life.

STUDY PURPOSE: To evaluate the evidence related to use of herbal medicine for prevention and treatment of chemotherapy-induced peripheral neuropathy
TYPE OF STUDY: Systematic review
DATABASES USED: 13 electronic databases including Medline, CENTRAL, EMBASE, AMED, China National Knowledge Infrastructure, Wanfang Database, CQVIP database, Korean Studies Information, DBPIA, Korea Institute of Science Technology Information, Research Information Center for Health Database, Korean Traditional Knowledge Portal, KoreaMed
YEARS INCLUDED: (Overall for all databases) through May 2017, no other limitations on publication date
INCLUSION CRITERIA: Randomized controlled trials that tested herbal medicine for preventing or treating CIPN. Participants in the studies were at least 18 years old, diagnosed with cancer, had received chemotherapy, and had CIPN diagnosed by clinical assessment.
EXCLUSION CRITERIA: Only the first treatment period data was analyzed for crossover trials. If the authors could not separate the results of the first and second periods in the crossover trial, they excluded the study. RCTs with unreliable or unavailable methods or results
TOTAL REFERENCES RETRIEVED: 819
FINAL NUMBER STUDIES INCLUDED: 28
TOTAL PATIENTS INCLUDED IN REVIEW: 2,174
SAMPLE RANGE ACROSS STUDIES: 31-186
KEY SAMPLE CHARACTERISTICS: Various solid tumors and one study in multiple myeloma, studies investigated oral herbals foot baths, IV, and fumigation. Oxaliplatin was used in 20 studies, paclitaxel was used in two, docetaxel was used in one, and various chemotherapy regimens were used in four studies.
PHASE OF CARE: Active anti-tumor treatment
The authors were unable to perform planned meta-analysis because of the heterogenicity of herbal treatments, doses, outcome measures, and small sample sizes.
Unable to draw any conclusions about the efficacy of herbal treatments for prevention or treatment of CIPN
