# Ashitaba Stem Juice **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/ashitaba-stem-juice **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-15 **Evidence Score:** 6 / 10 **Category:** Other **Also Known As:** Angelica keiskei, Ashitaba ## Overview Ashitaba Stem Juice is rich in chalcones, particularly xanthoangelol (XA) and 4-hydroxyderricin (4-HD), which are key to its health benefits. XA notably contributes to its anti-thrombotic properties by inhibiting PAI-1 production in various cell types and suppressing platelet activation. ## Health Benefits - Enhances cellular regeneration through its unique chalcone compounds, promoting tissue repair and renewal. - Supports [digestive health](/ingredients/condition/gut-health) by providing dietary fiber, which aids gut motility and nutrient absorption. - Modulates [immune function](/ingredients/condition/immune-support) with a rich profile of vitamins and antioxidants, strengthening the body's defenses. - Protects against [oxidative stress](/ingredients/condition/antioxidant) due to potent antioxidants like chalcones, contributing to [anti-aging](/ingredients/condition/longevity) effects. - Improves skin vitality by supporting [collagen production](/ingredients/condition/skin-health) and cellular health through Vitamin C and beta-carotene. ## Mechanism of Action Ashitaba Stem Juice contains potent chalcones, primarily xanthoangelol (XA) and 4-hydroxyderricin (4-HD), alongside flavonoids and phenolic compounds like chlorogenic acid derivatives. XA specifically demonstrates anti-thrombotic activity by inhibiting PAI-1 production in endothelial cells, adipocytes, and hepatocytes, and also suppresses platelet activation. These compounds additionally contribute to its traditional anti-diabetic and [anti-inflammatory](/ingredients/condition/inflammation) effects, further supporting cellular regeneration and [immune function](/ingredients/condition/immune-support). ## Clinical Summary Clinical research on Ashitaba Stem Juice's direct efficacy in humans is emerging, with current scientific understanding largely based on in vitro and animal studies. These studies primarily investigate isolated chalcone compounds, such as xanthoangelol, demonstrating their [antioxidant](/ingredients/condition/antioxidant) and [anti-inflammatory](/ingredients/condition/inflammation) potential. While traditional uses point to anti-thrombotic, anti-diabetic, and immune-modulating benefits, robust human-centric trials are needed to fully confirm these effects and mechanisms in vivo. ## Nutritional Profile - Dietary Fiber - Vitamin C - Beta-Carotene (precursor to Vitamin A) - Chalcones (Xanthoangelol, 4-Hydroxyderricin): Potent polyphenolic [antioxidant](/ingredients/condition/antioxidant)s ## Dosage & Preparation - Common forms: Fresh stem juice, powder, capsules. - Fresh Juice: Consume 30–50 ml daily for optimal health and vitality. - Smoothies: Blend 2–3 tablespoons into smoothies for a nutritional boost. - Diluted Tonic: Mix 2 tablespoons with water or herbal tea for an immune-supporting drink. ## Safety & Drug Interactions Information regarding the specific safety profile, potential side effects, drug interactions, or contraindications for Ashitaba Stem Juice is not provided in the available research. Consumers should exercise caution and consult a healthcare professional before use, especially if pregnant, nursing, or taking medications. ## Scientific Research Specific scientific studies on Ashitaba Stem Juice's direct efficacy in human clinical trials are emerging. Research primarily focuses on the in vitro and animal studies of its isolated chalcone compounds, demonstrating [antioxidant](/ingredients/condition/antioxidant) and [anti-inflammatory](/ingredients/condition/inflammation) potential. Further human-centric research is needed to substantiate direct health claims for the juice. ## Historical & Cultural Context Ashitaba has been a cornerstone of traditional Japanese medicine for centuries, particularly in the Izu Islands, where it is known as the 'Leaf of Tomorrow.' It was traditionally consumed to promote [longevity](/ingredients/condition/longevity), vitality, and overall well-being, with its fresh stem juice revered for supporting [digestion](/ingredients/condition/gut-health), [immunity](/ingredients/condition/immune-support), and cellular health. ## Synergistic Combinations Role: Concentrated phytonutrient/hydration vector Intention: Gut & [Microbiome](/ingredients/condition/gut-health) | Immune & [Inflammation](/ingredients/condition/inflammation) Primary Pairings: Spirulina (Arthrospira platensis); Chlorella (Chlorella vulgaris); Vitamin C (Ascorbic Acid); Maca Root (Lepidium meyenii) ## Frequently Asked Questions ### What is Ashitaba Stem Juice derived from? Ashitaba Stem Juice is the yellow exudate (AYE) extracted from the fresh stems of *Angelica keiskei*, a herbaceous plant native to Japan's Izu Islands. This traditional Japanese medicinal plant is recognized for its unique chalcone compounds. ### What are the main bioactive compounds found in Ashitaba Stem Juice? The primary bioactive compounds in Ashitaba Stem Juice are chalcones, mainly xanthoangelol (XA) and 4-hydroxyderricin (4-HD), which account for over 90% of its chalcone content. It also contains various flavonoids and other phenolic compounds, such as chlorogenic acid derivatives. ### How does Ashitaba Stem Juice support anti-thrombotic effects? Ashitaba Stem Juice's anti-thrombotic properties are primarily attributed to xanthoangelol (XA). XA has been shown to inhibit PAI-1 (plasminogen activator inhibitor-1) production in endothelial cells, adipocytes, and hepatocytes, and also suppresses platelet activation, contributing to blood clot prevention. ### What traditional health benefits are associated with Ashitaba Stem Juice? Traditionally, Ashitaba Stem Juice has been used for various health benefits, including anti-thrombotic, anti-diabetic, and anti-inflammatory effects. It is also believed to enhance cellular regeneration, support digestive health by providing dietary fiber, and modulate immune function with its rich profile of vitamins and antioxidants. ### What is the current state of scientific evidence for Ashitaba Stem Juice's efficacy? Specific scientific studies on Ashitaba Stem Juice's direct efficacy in human clinical trials are emerging. Research primarily focuses on in vitro and animal studies of its isolated chalcone compounds, demonstrating their antioxidant and anti-inflammatory potential. Further human-centric research is necessary to fully establish its benefits in clinical settings. ### Is Ashitaba Stem Juice safe to take during pregnancy or while breastfeeding? While Ashitaba has a long history of traditional use in Japan, limited clinical data exists specifically for pregnancy and breastfeeding populations. Pregnant and nursing women should consult with their healthcare provider before supplementing with Ashitaba Stem Juice, as some of its bioactive compounds may cross the placenta or enter breast milk. Safety in these populations has not been formally established through rigorous clinical trials. ### Does Ashitaba Stem Juice interact with blood thinning medications or anticoagulants? Yes, Ashitaba Stem Juice's documented anti-thrombotic properties may potentiate the effects of blood-thinning medications such as warfarin or aspirin, increasing bleeding risk. Individuals taking anticoagulant or antiplatelet drugs should inform their healthcare provider before using Ashitaba supplementation. Medical supervision is recommended to monitor for potential interactions and adjust dosing if necessary. ### What is the most effective form of Ashitaba Stem Juice supplement—juice, powder, or extract? Standardized extracts concentrate the bioactive chalcones and antioxidants from Ashitaba stem, making them typically more potent per serving than whole juice or powder forms. The bioavailability of chalcone compounds may be enhanced when consumed with dietary fat, which supports absorption of these lipophilic compounds. Fresh or freeze-dried juice preserves more enzymatic activity, while powders offer convenience, so the "best" form depends on individual absorption capacity and lifestyle preferences. ## References Sources: https://pubmed.ncbi.nlm.nih.gov/31083797; https://www.sciencedirect.com/science/article/abs/pii/S0024320518306906; https://www.frontiersin.org/articles/10.3389/fphar.2019.00424/full --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
