Cannabis medicines for nausea or appetite: the indications matter
Short answer: In the United States, some prescription cannabinoid medicines have FDA-approved uses for specific conditions. Those approvals do not establish that dispensary cannabis, CBD, or an edible treats general nausea or reduced appetite after age 50.
The narrow approved uses
FDA lists dronabinol products (Marinol/Syndros) for nausea and vomiting associated with cancer chemotherapy; dronabinol also has an indication for anorexia associated with weight loss in people with AIDS. Nabilone (Cesamet) is indicated for chemotherapy-associated nausea and vomiting. These are named prescription medicines and defined indications--not approval of cannabis as a plant or of every product containing THC or CBD.
NCCIH makes the same distinction in its evidence summary. It notes that the research for cannabinoid medicines and chemotherapy-related nausea largely dates from the 1980s and 1990s, so it reflects earlier treatment choices. That history is another reason not to generalize the finding to all causes of nausea or all current products.
What this does not show
These sources do not establish that cannabis treats unexplained or persistent nausea, ordinary appetite loss, or symptoms for every adult over 50. They do not justify a consumer dose or product recommendation. FDA warns that unapproved cannabis-derived products have not been reviewed as safe and effective for the many conditions for which they are marketed.

Quick answers
Which uses have a specific U.S. prescription indication?
FDA lists specific prescription cannabinoid medicines for chemotherapy-associated nausea and vomiting; dronabinol also has an indication for anorexia associated with AIDS-related weight loss.
Does that mean cannabis treats everyday nausea or low appetite?
No. A drug approval for a named medicine and condition does not establish benefit from retail cannabis or for other causes of symptoms.
