3. Medicinal Uses:

Prebiotic, Hypoglycemic, Nutritive Tonic, Galactagogue, Diuretic, Hepatic Tonic.

Medicinal Parts:

The tuber is the primary part used, both as food and medicine.

· Tuber: Eaten raw or cooked for its health benefits.

4. Phytochemicals specific to the plant and their action.

Inulin (a Fructan): The key compound. A soluble, non-digestible fiber that acts as a powerful Prebiotic, selectively feeding beneficial gut bacteria (Bifidobacteria, Lactobacilli). This action supports Gut Health, Immunomodulation, and contributes to Hypoglycemic and Hypolipidemic effects.

Fructooligosaccharides (FOS): Similar to inulin, these are short-chain fructans with strong Prebiotic activity.

Potassium: A vital mineral that supports its Diuretic and Electrolyte-balancing actions.

5. Traditional and Ethnobotanical uses covering the Medicinal uses.

Grahani (Malabsorption) & Agnideepana (Digestive Fire)

Formulation: Cooked tuber as part of the diet.

Preparation & Use: The tuber is consumed to improve gut flora, relieve constipation, and support overall digestive health. Its sweet taste (Madhura Rasa) is nourishing.

Reasoning: Inulin and FOS serve as food for probiotic bacteria, restoring a healthy gut microbiome, which is foundational to digestion (Agni) and nutrient absorption.

Madhumeha (Diabetes)

Formulation: Raw or cooked tuber in meals.

Preparation & Use: Incorporated into the diet as a starchy vegetable that does not spike blood sugar sharply.

Reasoning: Inulin is not broken down into simple sugars in the upper GI tract, leading to a lower glycemic response compared to potatoes or wheat flour.

Stanyajanana (Galactagogue) & Balya (Strength)

Formulation: Tuber soup or stew.

Preparation & Use: Used as a nourishing food for nursing mothers and convalescents to build strength and support milk production.

Reasoning: Its role as a nutritive tonic and its positive effects on overall metabolism and gut health support the body's increased nutritional demands.

6. Healing recipes, Teas, Decoctions and Culinary use (if any):

It is a versatile culinary vegetable, eaten raw in salads (nutty, crunchy) or cooked (sweet, soft).

Prebiotic Raw Salad

Purpose: To maximize prebiotic intake for gut health.

Preparation & Use:

· Thinly slice or julienne fresh, scrubbed Jerusalem artichokes.

· Toss with lemon juice, olive oil, salt, and herbs. Eat raw to preserve inulin.

Digestive and Galactagogue Soup

Purpose: A nourishing, gut-supportive soup.

Preparation & Use:

· Sauté onions, garlic, and diced Jerusalem artichokes.

· Add vegetable broth and simmer until tender.

· Blend until smooth, season, and serve. Add coconut milk for extra nourishment.

7. Disclaimer:

Jerusalem artichokes are safe and highly nutritious for most people. However, due to the high inulin/FOS content, introducing them in large amounts suddenly can cause significant gas, bloating, and abdominal discomfort as gut bacteria ferment the fibers. Start with small servings (1-2 tbsp) and increase gradually. Individuals with FODMAP sensitivities or Small Intestinal Bacterial Overgrowth (SIBO) may need to avoid them. This information is for educational purposes.
