Horehound (Marrubium vulgare) has been used traditionally for digestive irregularities such as bloating, loss of appetite or dyspepsia. It has also been used for acute bronchitis and nonproductive coughs. Horehound contains saponins and hydroxycinnamic derivatives which have demonstrated antioxidant properties.

Basil (Ocimum basilicum), a common culinary herb, contains vitamin C and rosmarinic acid, both of which have demonstrated antioxidant properties. Basil also has antimicrobial properties.

Sage (Salvia officinalis) contains a variety of flavonoids, primarily genkwanin, 6 methoxygenkwanin, luteolin, rosmarinic, labiatic and carnosic acid, all of which possess antioxidant properties. Additionally sage has been used internally for stomach upset, excessive perspiration, and for inflammations of the mucous membranes of nose and throat.
