1. Carrying solid drugs: Plant hollow capsules can be used to carry solid drugs, making them more effective in exerting their effects in the human body. In most cases, hollow capsules do not have any side effects on the body.

2. Reduce the stimulation of drugs on the digestive system: As plant hollow capsules are made from natural seaweed, they can reduce the stimulation of drugs on the digestive system, especially for drugs that require intestinal absorption.

3. Increase drug stability: Plant hollow capsules can provide a closed environment, effectively protecting drugs from external environmental factors, thereby improving drug stability and shelf life.

4. Improve the convenience of medication use: Plant hollow capsules can protect drugs from digestion in the mouth and stomach, making them more easily absorbed by the human body during the medication process, thereby increasing the convenience of medication use.
