Purple Loosestrife - Lythrum salicaria
Purple Loosestrife, Lythrum salicaria, was introduced to the Americas in the 1800s and has become widely invasive. It grows in marshy areas and crowds out native species such as cattails, but it is very useful. Purple loosestrife is antimicrobial, antioxidant, styptic, vulnerary (wound healing), antifungal, astringent, demulcent, anti-inflammatory, and antinociceptive (pain blocking). In Traditional Chinese Medicine it is used to treat dysentery. I collect it just as it flowers, when it is richest in flavonoids. Flavonoids are anti-inflammatory, antioxidant, anticancer, antiviral, cardioprotective, and neuroprotective.
It is useful as a tincture or cream to treat fungal skin infections and hemorrhoids. It can be used as an antibacterial and antifungal gargle for sore throat and bleeding gums. It is used for gastrointestinal upset, IBS, and diarrhea. As a tea it is used for respiratory illness, bacterial infections, and menstrual problems. It is used as a douche for vaginitis and as a styptic nasal douche for nosebleeds.
Purple loosestrife has antimicrobial properties and has been demonstrated to have activity in vitro against Candida albicans, Staphylococcus aureus, Proteus mirabilis, E. coli, Micrococcus luteus, and Cladosporium cucumerinum. 1

Apart from phenolics the presence of some non-polar compounds belonging to different chemical groups such as steroids, triterpenes, phthalates, coumarins was confirmed in extracts prepared from L. salicaria." 2
