Plant Family: Asteraceae (Daisy family)
Visual Description: Tall, wiry stems with bright blue flowers and ragged, dandelion-like leaves. Typically grows wild along roadsides and in poor soil.
Edibility: Roots (roasted or boiled), young leaves (raw or cooked). Flowers edible but mildly bitter. Roots when roasted and ground make an excellent and healthy substitute for coffee.
Toxicity Notes: Avoid if severely allergic to ragweed family. No toxic lookalikes, but do not harvest roadside plants due to contamination from exhaust and polluted soil.
| Ailment / When to Use | Part Used | Preparation and Dose | How does it Actually Work? | Source |
|---|---|---|---|---|
| Sluggish digestion, bloating after meals | Roasted or dried root | Simmer 10 g root in 500 mL water for 20 minutes. Drink 1 cup before meals for 1 to 2 weeks. | Root bitterness stimulates bile flow. This helps digestion and relieves gas. | [1] |
| High blood sugar, insulin resistance | Cooked root or decoction | Eat 1/2 cup boiled root with meals or drink 1 cup decoction 30 minutes before eating. | Inulin slows glucose absorption and supports insulin sensitivity through gut flora. | [2] |
| Liver sluggishness, hormonal imbalance | Roasted root decoction | Drink 1 cup of root tea daily for 2 to 3 weeks. Take a 1-week break before repeating. | Bitters activate liver detox pathways and promote bile movement. | [3] |
| PMS bloating, water retention | Leaf infusion | Steep 1 tsp dried leaf in 250 mL water. Drink up to 3 cups per day for 5 days. | Diuretic effect increases kidney filtration and helps reduce swelling. | [4] |
| Constipation, poor gut flora | Inulin-rich root | Eat raw or lightly cooked root daily or add powdered inulin to food (2 to 5 g daily). | Inulin feeds beneficial bacteria and softens stool bulk. | [5] |

|---|---|---|---|---|
| Inulin | Prebiotic fiber | Feeds beneficial gut bacteria | Digestion, blood sugar balance, immunity | [1] |
| Chicoric acid | Polyphenol antioxidant | Reduces oxidative stress | Immunity, inflammation | [2] |
| Lactucin, Lactucopicrin | Sesquiterpene lactones | Modulate nervous system | Pain relief, relaxation, sleep | [3] |
| Manganese | Trace mineral | Enzyme cofactor, antioxidant support | Metabolic health | [4] |
| Vitamin K | Fat-soluble vitamin | Blood clotting, bone health | Bone and cardiovascular health | [5] |

|---|---|---|---|---|---|
| Compacted or degraded soil | Breaks up hard soil layers | Deep taproot | Let grow one full season; chop and drop | Improves aeration, water penetration | [1] |
| Low nutrient availability | Accumulates and mobilizes nutrients | Root and foliage | Compost biomass or let decompose in place | Returns calcium, magnesium, potassium to topsoil | [2] |
| Erosion-prone slopes | Soil stabilizer and pioneer | Holding roots, drought tolerance | Broadcast seed in fall or spring | Reduces erosion, supports succession | [3] |
| Lack of pollinators | Pollinator attractant | Flowering stalks | Let flower fully near crops/edges | Supports bees, hoverflies in recovery zones | [4] |
