"Quacks and Nostrums" is a 20-minute film from 1959. We meet a woman who purchases a "South Seas" herbal tea with alleged powerful healing properties. The woman's son becomes concerned and visits the family doctor to ask him what he thinks. The doctor, who has all the time in the world to chat, recommends that he visit the local branch of the Food and Drug Administration to learn more about what the government is doing to crack down on snake-oil paddlers. He does, and a gentleman from the FDA invites him into his office for a chat, and he is shown a number of bizarre quack remedies confiscated by the FDA.
Unfortunately, the man's mother doesn't listen to her son's pleas to seek legitimate medical help and develops a serious gall bladder problem that is unaffected by the tea she bought from Alooka Ka'humana. I won't spoil the ending for you.
