Black eyed susan (Rudbeckia hirta):
 Black-eyed Susan is native to the eastern United States but has spread to the rest of North America. It can be either biennial or perennial depending on the climate and is found growing wild in fields, roadsides, and forests. The flowers typically bloom from June to August.
 The plant also is a traditional Native American medicinal herb in several tribal nations; believed in those cultures to be a remedy for colds, flu, infection, swelling and for snake bites. Typically used as a poultice, it is applied directly to the skin. It boosts immunity and fight infections and is also an astringent when used in a warm infusion as a wash for sores and swellings.
Limonene is found in some plants of the Asteraceae family which is a natural colorless liquid used for clensing and contains anti-stress and sedative properties.
 

Blue vervain (Verbena hastata):
Commonly grown across North America, this plant is hardy and drought resistant. It can grow in disturbed sites and is found in meadows, thickets, pastures, and forests. It begins to bloom during the late summer.
 Some people apply verbena directly to the skin through a poultice to treat poorly healing wounds, abscesses and burns; joint pains and itching caused by allergic reactions or blisters.
The plant contains cornin, hastatoside, and verbenalin which is used primarily as a soothing and sleep-promoting component.
