I had a dry cough left over from COVID a month ago, and my doctor didn't really prescribe anything. A friend suggested I drink sea buckthorn oil or gargle with it. Will it actually help or is it just placebo?
Sea buckthorn oil contains vitamins and antioxidants that are genuinely beneficial for mucous membranes, but it's not a cure-all for post-COVID cough - more of a supportive remedy for comfort. If a month has passed and the cough won't go away, you shouldn't just stick with the oil; push for a more thorough examination from your doctor or even ask for a pulmonologist's consultation - sometimes after COVID you need specialized respiratory rehabilitation, not just throat soothing. You can try gargling with the oil if you really want to, but it'll mostly give you temporary subjective relief rather than actually solve the problem.
Sea buckthorn oil has anti-inflammatory properties and can soothe an irritated throat, but that's more symptomatic relief than actual treatment for post-COVID cough. If a month has passed and the cough is still there, it's worth seeing another doctor or a pulmonologist - sometimes after COVID you need specialized rehabilitation or additional testing, not just home remedies. The oil definitely won't hurt, but don't expect it to work miracles.
