Perilla seeds, also known as su zi (苏子) or zi su zi (紫苏子) in Chinese, are the tiny powerhouses of the Perilla frutescens plant. This annual herb, belonging to the mint family, has been a staple in Traditional Chinese Medicine (TCM) and Asian cuisine for centuries. Let’s dive into the world of su zi and explore its fascinating properties and potential health benefits.
What is Su Zi?
Su zi refers to the fruit of the Perilla plant, which is native to East Asia (such as Vietnamese Perilla). These small, oval-shaped seeds are typically grayish-brown to dark brown in color, with a distinct network-like pattern on their surface. They have a mild, nutty aroma and a slightly pungent taste.
Fun fact: In Korea, perilla leaves are often called “sesame leaves,” even though they’re not related to sesame at all!
Nutritional Profile
Su zi packs a punch when it comes to nutrition. These little seeds are:
- Rich in omega-3 fatty acids, particularly alpha-linolenic acid (ALA)
- A good source of protein
- Packed with minerals like calcium and iron
- Contain various vitamins, including vitamin B1 (thiamine)
Potential Health Benefits
1. Respiratory Support
In TCM, su zi is often used to:
- Relieve coughs
- Clear phlegm
- Soothe asthma symptoms
These traditional uses align with modern research suggesting that perilla seeds may have anti-inflammatory properties that could benefit respiratory health.
2. Digestive Aid
- Promote smooth digestion
- Relieve bloating and gas
- Help with constipation
Its mild laxative effect may be due to its high oil content and fiber.
3. Heart Health
The high omega-3 content in su zi may contribute to:
- Lowering cholesterol levels
- Reducing inflammation
- Supporting overall cardiovascular health
4. Skin Health
Some studies suggest that the oils in su zi might:

How to Use Su Zi
There are several ways to incorporate su zi into your diet:

- In beverages: Brew the seeds into a tea for a soothing drink.
- As an oil: Su zi oil can be used in cooking or as a dietary supplement.

Precautions
While su zi is generally safe for most people, it’s important to note:
- Pregnant women should consult a healthcare provider before using su zi medicinally.
- Those with bleeding disorders or taking blood thinners should use caution, as su zi may have blood-thinning effects.
- Some people may be allergic to perilla seeds, so start with a small amount if you’re trying them for the first time.
The Bottom Line
Su zi, or perilla seeds, offer a unique blend of flavor and potential health benefits. From supporting respiratory health to aiding digestion, these tiny seeds pack a powerful punch. While more research is needed to fully understand their effects, su zi has been a trusted component of traditional medicine and cuisine for generations.

Remember, as with any dietary supplement, it’s always best to consult with a healthcare professional before making significant changes to your diet or starting any new herbal remedies.
