Young plants look very different from the mature, flowering plant, and have often fooled me into believing it was something desirable. Now I know better - even though the small white daisies are cute, the fluffy seedheads are messy, and give rise to an abundance of seedlings.

I'm Tham from Malaysia.
The eastern daisy fleabane is actually a powerful herb for
the heart. While searching Medline for herbs which might
inhibit the latest heart marker enzyme, Lp-PLA2 (lipoprotein
-phospholipase A2), I came across this Korean study.
Searching further for this herb, I came across your website.

Flowers of Erigeron annuus L. were extracted with 80% aqueous
MeOH, and the concentrated extract was partitioned with EtOAc,
n-BuOH, and H2O. Repeated silica gel and ODS column
chromatography of the EtOAc fraction led to the isolation of a
sterol, through activity-guided fractionation, using ACAT inhibitory
activity measurements. From the physico-chemical data, including
NMR, MS, and IR, the chemical structure of the compound was
determined to be an ergosterol peroxide (1), which has been
isolated for the first time from this plant. This compound exhibited
hACAT-1 and Lp-PLA2 inhibitory effects, with inhibitory values of
51.6 +/- 0.9 and 51.7 +/- 1.2%, at a treatment concentration of 0.23 mM.
