Perilla leaves, also known as shiso or perilla frutescens, are widely used in Asian cuisine, especially in Vietnam, Japan, and Korea. While many people see it simply as an herb to enhance flavor, doctors have revealed that eating perilla leaves can bring a number of unexpected health benefits. However, like any food, it also requires proper use to avoid potential side effects.
1. Rich in Anti-Inflammatory Compounds
Doctors found that perilla leaves contain rosmarinic acid, a natural compound known for its strong anti-inflammatory effects. This compound helps reduce swelling, soothe allergies, and relieve symptoms of conditions like arthritis. Regular consumption may help the body fight chronic inflammation more effectively.
2. Helps Improve Digestion
Perilla leaves have long been used to treat bloating, nausea, and stomach discomfort. The essential oils in the leaves help the digestive system relax and improve intestinal movement. Drinking warm perilla tea or adding the leaves to meals can help reduce indigestion after eating oily or heavy foods.
3. Supports Stronger Immunity
Thanks to its high levels of vitamin C, flavonoids, and antioxidants, perilla leaves help strengthen the immune system, protect cells from free radical damage, and support the body in fighting viruses and bacteria. During seasonal changes or flu season, perilla tea is often recommended to support natural immunity.
4. May Help Reduce Stress and Anxiety
Perilla leaves contain compounds that can have a calming effect on the nervous system. Some studies suggest that perilla may help balance mood, reduce nervous tension, and support sleep. A warm cup of perilla leaf tea before bed may help promote relaxation.
5. Supports Respiratory Health
In traditional medicine, perilla leaves are often used to alleviate symptoms of cough, sore throat, and mild asthma. Its essential oils can help open airways and reduce irritation. This makes it a natural option for easing respiratory discomfort.
6. Who Should Be Careful When Eating Perilla Leaves
Although perilla leaves are generally safe, doctors warn that overconsumption can lead to:
- Lightheadedness or fatigue in some individuals
- Increased risk of bleeding for people taking anticoagulant medication
- Possible allergic reactions for those sensitive to aromatic herbs
- If you have chronic health conditions, consult a doctor before using perilla as a frequent remedy.
7. How to Use Perilla Leaves Safely
To enjoy the benefits:
