- Hyssop (Hyssopus officinalis) is a semi-evergreen shrub growing up to about 2 ft (60 cm), with narrow leaves and clusters of bright blue, two-lipped flowers. Known since ancient times as a “cure-all” for respiratory ailments, it clears congested phlegm and supports recovery from infections. Hyssop also has antiseptic qualities beneficial for cuts, abrasions, and insect bites.Mullein (Verbascum thapsus) is an upright biennial reaching up to about 6½ ft (2 m), with distinctive gray-green, oval to lance-shaped leaves that are softly hairy, and tall spikes of bright yellow flowers. Leaves and flowers both contain saponins that assist in loosening mucus, making mullein especially beneficial for respiratory conditions such as asthma, COPD, dry coughs, and congestion. Mullein root is specifically valued for lower back pain and inflammation.
