This study is a single blind, randomized controlled trail. condition/disease: Post-accident syndromes after acute phase treatment/intervention: herbal medicine treatment strategy

The Korean herbal medicine is a complex extract of medicinal herbs prescribed by a Korean medicine doctor who has completed specialized education to diagnose the health condition and symptoms of patients with post-traffic accident syndromes. This treatment is known to relieve the post-accident syndromes and improve health. However, there are no studies examining the efficacy of Korean herbal medicine alone.

So, the investigators will conduct a randomized controlled trials to verify the efficacy and safety of Korean herbal medicine. From July, 2021 to May, 2022, the investigators recruited 40 patients who are suffered from post-accident syndromes with the numeric rating scale(NRS) over 5. For experimental group(the Korean herbal medicine treatment group, n=20), the investigators conducted Korean medicine treatment for 4 weeks(28 days), and for control group(the Non-Korean herbal medicine treatment group, n=20), just Korean medical treatment(acupuncture, pharmacoacupuncture, cupping, and chuna) has been conducted. For these two groups, the investigators compared NRS, Impact of Event Scale-Revised-Korean(IES-R-K), 5-level EuroQol 5-dimension(EQ-5D-5L), Short-Form-12 Health Survey version2(SF-12 v2), and Patient Global Impression of Change(PGIC).
