What traditional systems uses this plant?
This plant, Dichroa febrifuga, has been utilized for centuries in Traditional Chinese Medicine to treat various febrile illnesses and inflammatory conditions. Known as Qing Hao in its local context, the root is specifically prepared to clear heat and dispel wind-heat from the body. Historical practitioners often prescribed it to manage symptoms of malaria and other infectious diseases characterized by high fever. Its chemical properties were traditionally harnessed to balance internal temperatures and reduce swelling. This long-standing medicinal history provided the foundation for modern scientific investigations into its antimalarial efficacy.
According to a study published by "Mitochondrial DNA. Part B, Resources", Dichroa febrifuga has a long history in traditional Chinese medicine and is seen as a medicinal plant. The first complete chloroplast genome determined for this plant was 157,647 bp in length. This genome included a large single-copy region of 86,728 bp, a small single-copy region of 18,675 bp, and a pair of inverted repeat regions of 26,122 bp. The genome encoded 128 genes, which consisted of 84 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on 20 complete cp genome sequences revealed that Dichroa febrifuga was the sister of the ancestor of the reported Hydrangeeae species.

What are the pharmacological activities of Dichroa febrifuga?
This plant has significant pharmacological activities including potent anti-inflammatory, antibacterial, and anti-malarial properties. Its chemical constituents are particularly effective at inhibiting the growth of malaria-causing parasites such as Plasmodium falciparum. Researchers have also observed that its extracts can suppress inflammatory responses by modulating specific biochemical pathways in the body. Additionally, the plant demonstrates a capacity to combat various bacterial strains, making it a subject of interest for antimicrobial drug development. These diverse therapeutic effects highlight its potential value in both traditional medicine and modern pharmacology.
According to a study published by "Acta pharmacologica Sinica", aqueous extract from Dichroa febrifuga root (AEDF) shows anti-inflammatory effects in the rat liver during lipopolysaccharide (LPS)-induced sepsis. When rats were challenged with 8 mg/kg of LPS, the levels of nuclear factor (NF)-kappaBp65 were markedly up-regulated and (I)-kappaBalpha was down-regulated. However, the administration of AEDF at 100 mg/kg inhibited the induction of NF-kappaBp65 and the degradation of I-kappaBalpha in the liver of these rats. Immunohistochemical analysis revealed that rats pretreated with AEDF showed a slight decline of NF-kappaBp65, TNF-alpha, and iNOS, alongside an increase in I-kappaBalpha in the hepatocytes. Consequently, AEDF may act as a therapeutic agent for inflammatory disease through the regulation of inflammation-related proteins.
The primary pharmacological activities of this plant are shown in the list below.
- anti-inflammatory
- antibacterial
- antimalarial
What medicinal compounds this plant contains?
This plant contains the medicinal alkaloid febri fugin e, which is primarily isolated through the use of a MeOH extract.
