Shiso, also known as perilla, is a vibrant and versatile herb celebrated across various cultures, particularly in East Asia. While often recognized for its distinct flavor and culinary applications, shiso boasts a wide array of uses, ranging from traditional medicine to natural dyeing. This article delves into the multifaceted world of shiso, exploring its culinary versatility, potential health benefits, and other intriguing applications.
Culinary Applications of Shiso
Shiso’s unique flavor profile, often described as a blend of mint, basil, anise, and cilantro, makes it a prized ingredient in many cuisines. Its leaves, seeds, and even sprouts offer diverse culinary possibilities.
Using Shiso Leaves in Cooking
The leaves are the most commonly used part of the shiso plant. There are typically two main varieties: green shiso (aojiso) and red shiso (akajiso). Green shiso is often used fresh, while red shiso is more frequently pickled or used for coloring.
Green shiso leaves are frequently used as a garnish for sashimi, offering a refreshing counterpoint to the richness of the fish. They can also be finely chopped and added to salads, soups, and noodle dishes. Its aroma is especially enhanced when the leaves are bruised or slightly torn. The leaves are a good source of vitamins and minerals, adding nutritional value along with flavor.
Red shiso, with its bolder flavor, is often used to make umeboshi (pickled plums), imparting both color and a characteristic flavor. It is also used to make shiso juice, a refreshing summer drink, and to color other pickled vegetables.
Shiso Seeds and Sprouts
Shiso seeds, known as perilla seeds, are also edible and offer a nutty flavor. They can be toasted and used as a topping for rice or vegetables. The seeds contain a high amount of alpha-linolenic acid (ALA), an omega-3 fatty acid, making them a healthy addition to your diet.
Shiso sprouts, or shoots, offer a milder flavor than the mature leaves. They are often used as a garnish or added to salads and soups for a delicate flavor and texture.
Shiso Oil
Shiso oil is extracted from the seeds and is highly valued for its high ALA content. It’s often used as a dietary supplement and in some culinary applications, though it should be used sparingly due to its strong flavor.
Potential Health Benefits of Shiso
Beyond its culinary uses, shiso has a long history in traditional medicine and is being investigated for its potential health benefits.
Anti-Allergic Properties
One of the most promising areas of research regarding shiso is its potential to alleviate allergy symptoms.

How should Shiso herb be stored to maintain freshness?
To keep shiso fresh for as long as possible, it’s best to treat it like fresh-cut flowers. Trim the stems and place the shiso sprigs in a glass or jar filled with water, covering the leaves loosely with a plastic bag. This helps to maintain humidity and prevent wilting. Store the jar in the refrigerator.
Alternatively, you can wrap the shiso leaves in a slightly damp paper towel and then place them in a perforated plastic bag.
