Yes, you can consume aloe vera and amla juice during winter, even with a cough, but with a few precautions. Both are excellent for boosting immunity, especially amla, which is rich in Vitamin C. However, cold liquids can irritate a sensitive throat and worsen a cough. To prevent this, avoid consuming them chilled. Instead, dilute the juices with warm water and add a spoonful of honey to help soothe your throat. It is best to drink this at room temperature. If your cough persists for more than a few days or worsens, please consult a doctor for a proper check-up.
