Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly allocated to intervention group (CHM plus WM) or control group (CHM placebo plus WM) in equal ratio (1:1). The randomization codes will be kept in sealed opaque envelopes and the envelopes will be opened sequentially for each participant only after participant details are written on the outside of the envelope. A number code inside the envelope will correspond with a package number that will contain 12 weeks of either real CHM granule or an identically packaged placebo granule. Neither participant nor trialists will know what package the participant has been randomised to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation numbers will be generated by computer program with sequenced blocks (blinded block number).
Masking / blinding

Statistical methods / analysis
Baseline demographic characteristics such as gender and age will be analysed by chi square test or t test to determine equivalence between the two groups. Variables showing baseline imbalance will be taken into consideration when conducting data analysis (using the variables as covariates or performing sensitivity analysis to reveal the relationship between the variables and the outcome measures). Intention-to-treat analysis will be applied to outcome data to minimise bias due to withdrawals, all missing data will be replaced using the last observation carried forward (LOCF) method. Sensitivity analysis will be applied to measure changes to data output as a result of using the LOCF. Continuous data will be presented as means and standard deviation (SD), or 95% confidence interval (CI). Dichotomies data such as the percentage of participants achieving PASI 75 will be presented at Risk Ratio (RR) and 95% CI. P value =0.05 will be considered as statistically significant when comparing two groups.

Summary
Brief summary
Psoriasis currently has no cure. Whilst new therapies manage severe psoriasis well mild-moderate conditions have evidence of poor management. Chinese medicine regularly treats psoriasis successfully in a clinical scenario. This study will test a previously researched herbal formula and evaluate its efficacy when integrated with standard conventional therapy (calcipotriol). The study will randomize participants to either a herbal medicine plus calcipotriol group or a placebo plus calcipotriol group and compare changes in symptom severity, quality of life and blood markers for changes after 12 weeks of the intervention. It will also assess the safety of integrating the two therapies and acceptability of the treatment as well as assess any significant difference between health resource utilization of the two groups.
