There is a plant on the volcanic islands south of Tokyo whose name is a small poem. Ashitaba — 明日葉 — translates as "tomorrow's leaf," from the observation that when a leaf is picked in the morning, a new shoot is often visible by the next day. That remarkable regenerative vigor gave the plant its name, and made it a fixture of daily life in the Japanese coastal communities where it grows.
This guide covers what ashitaba is, how it has traditionally been enjoyed, how to take it, and what to look for in a quality ashitaba powder.
What Is Ashitaba?
Ashitaba (Angelica keiskei) is a leafy green plant in the same botanical family as carrots, celery, and angelica. It is native to the Izu Islands and the Pacific coast of Japan, where it thrives in mineral-rich volcanic soil and sea air.
The plant is distinctive in two ways. First, its vigor: ashitaba regrows quickly after harvest — the trait behind its name. Second, its golden sap: cut a stem and it weeps a yellow resin, the plant's signature and the source of naturally occurring compounds called chalcones, which give the sap its color. Ashitaba powder is made from the harvested leaves and stems, dried and milled into a fine green powder.
Traditional Use — Japan's Coastal Daily Green
On the Izu Islands, ashitaba has been part of the everyday table for generations — eaten as a vegetable, brewed as tea, folded into noodles and tempura. Like moringa in South Asia or nettles in Europe, it is a regional daily green: a plant valued not for occasional use but for steady presence, traditionally enjoyed to support vitality and balance as part of daily life.
That daily-ritual character is what places ashitaba naturally alongside the tonic herbs — botanicals taken consistently, over time, as nourishment.
How to Take Ashitaba Powder
Ashitaba has a fresh, grassy, slightly bittersweet green flavor — close to a wilder matcha. Ways to enjoy it:
- As tea — whisk ½ teaspoon into warm (not boiling) water, the traditional island preparation.
- In smoothies — pairs well with pineapple, banana, ginger, and citrus.
- In a green latte — with steamed nut milk and a touch of honey.
- In food — stir into dressings, or dust over rice, soups, and bowls.
Start with ½ teaspoon daily. As with all daily greens, it is traditionally enjoyed consistently over time.
Sourcing & Quality — What to Look For
- True Angelica keiskei. Ashitaba is sometimes confused or adulterated with related plants; a trustworthy source names the species.
- Leaf and tender stem, nothing else. Quality powder comes from the green, growing parts of the plant — with no fillers or blends.
- Careful drying. Gentle, low-heat drying preserves the vivid green color and fresh flavor; dull powder suggests rough handling.
- Third-party lab tested. Independent laboratory testing verifies purity.
Sun Potion's Ashitaba is milled from the leaf and tender stem with nothing added, and is third-party lab tested.
