What are some natural remedies for low blood pressure?

Hypotension: Increasing your salt intake - chicken soup is highly recommended! - is one of the easiest and often prescribed remedies for slight hypotension. You did not include your actual blood pressure so this is a simple answer not considering any other health factors or concerns. Please see a doctor to make sure that you are being treated appropriately. Be careful.

Low blood pressure: No need to treat unless you are dizzy or black out with low blood pressure. The treatment is to increase fluid and salt intake in those instances.

Treat if symptoms: Your doctor may have you increase salt intake for symptomatic low BP especially if it drops a lot upon standing. Using thigh high support stockings may also help. Your doctor may also use medications such as mididodrine and fludrocirtisone in which case careful follow up is essential.
