Does the herb mullin help with lung cancer?

Certain compounds in mullein's leaves and flowers are thought to act as demulcents or expectorants. Demulcents are substances that calm irritation or inflammation in the skin or internal parts of the nose, mouth, or throat. Expectorants are agents for stimulating the production or secretion of phlegm especially from the lungs. It will not cure any cancer, but help with cough.

Ran an online search, and there is NO such herb as "Mullin", so, please check your name and repost. Would like to be encouraging, but am NOT aware of any herb or supplement or vitamin that can help with lung cancer; wish I could.
