Objectives: Ciclosporin and sirolimus, two immunosuppressive agents with narrow therapeutic windows, are mainly metabolized by Cytochrome 3A4 (CYP3A4). A clinical case [highlighted] of toxic blood levels of these drugs after the consumption of a '24-flavours' tea was reported. This study aims to identify the causative ingredients [end highlight] of the 24-flavour herbal tea in the inhibition of CYP3A4 metabolism.

Methods: Two commercially available 24- flavour tea products purchased in Hong Kong and the six plant constituents were tested for their CYP3A4 inhibitory effects utilizing an in- vitro fluorometric assay.

Key findings: Of the commercially available teas available in Hong Kong, the most potent inhibitory effect was observed with the tea consumed in the initial clinical case. Of the six universal constituents, [highlight] chrysanthemum 5 the greatest inhibitory effect, iW LEW C50 of 95.7 ug/ml. Dandelion, liquorice and bishop's weed have IC50 of 140.6, 148.4 and 185.5 pg/ml, respectively. Field mint and Japanese honeysuckle have wearker inhibitory effect on CYP3A4 with IC50 of 1153.3 and 1466.6 ug/ml.

PRESS RELEASE
Groundbreaking myalgic encephalomyelitis study identifies over 250 core genes, shared biology with long COVID, and dozens of drug repurposing opportunities
The study reinforces that ME is a complex multisystemic condition with a clear genetic basis and lays the foundation for future clinical trials that could be faster to recruit and more likely to succeed
Read our FAQs

OXFORD, UK – 4 December 2025 – PrecisionLife today announced new findings from the most detailed genetic analysis of myalgic encephalomyelitis (ME, also known as ME/CFS) ever conducted, revealing more than 250 core genes associated with the disease, including 76 genes linked with long COVID, and uncovering dozens of drug repurposing opportunities supported by genetic biomarker tests, offering potential for faster and lower-risk routes to developing targeted treatments.

The study, now available as a pre-print and submitted for peer review, applied PrecisionLife's AI-led combinatorial analytics platform to analyze genomic data from two DecodeME cohorts together with UK Biobank to confirm reproducibility of results across three independent datasets. The analysis identified 7,555 genetic variants (including the 8 identified by the recent DecodeME GWAS study ), that were consistently associated with increased disease risk in three different populations.
