Since you are visiting a patient with hypertension, you should bring mountain plant foods as gifts, which are rich in acid and vitamin C, and can soften blood vessels. You can also bring some fruits that patients usually like to eat, such as bananas, oranges, grapes, and other fruits that are good for health.
In addition, what patients with hypertension need most is to check their blood pressure frequently to understand their physical condition at any time, so I think it is definitely a good gift for you to give the patient an electronic blood pressure meter, and the patient should like it more.
You can also give the patient something that he likes and is interested in. For example, if your relative likes fishing, you can give him a fishing rod he likes. If your relative likes playing chess, you can give him a good chess set. In short, as long as you cater to his preferences, he will definitely be very happy.
