Turmeric
Turmeric (Curcuma longa) is the golden rhizome at the heart of South Asian cooking, dried and brewed (or stirred in as powder) into a warm, earthy, slightly peppery and bitter golden infusion. On its own it is more savory and resinous than sweet, which is why it is usually paired with ginger, black pepper, citrus, or milk and honey, as in golden milk. It is naturally caffeine-free, and its vivid color comes from curcumin, the plant's principal pigment.
Quality turmeric for tea, whether cut dried root or powder, has a deep, vivid orange-gold color and a warm, earthy, slightly peppery aroma; pale, dull, or musty material is old or low-grade. Powder is more intense and colors the cup instantly but settles to the bottom, while cut or sliced dried root gives a cleaner, clearer infusion. A bright golden liquor with a warm, earthy, faintly bitter character is what you want. Because turmeric is often blended for golden-milk-style drinks, check that any blend lists real spices rather than just flavoring. Fresh, vivid color and a strong earthy smell are the best quality signals.
Curcuma longa is native to South and Southeast Asia and is cultivated heavily in India, which produces and consumes the majority of the world's turmeric. The rhizomes are boiled or steamed, dried, and then ground to powder or cut for infusion; the deep color comes from curcuminoids, chiefly curcumin. It has thousands of years of use in Indian cooking and in Ayurvedic tradition, where it is one of the most esteemed spices.
As a dense root, turmeric benefits from heat and time: use about 1 g per 100 ml of cut root, or a half teaspoon of powder (around 2 g per 250 ml cup), water at 95 to 100°C, steeped 7 to 10 minutes or gently simmered. A pinch of black pepper and a little fat (milk or a drop of oil) are traditionally added, as they are thought to help carry curcumin, which is otherwise poorly soluble in water. It is caffeine-free and does not turn bitter from long steeping. Cut root re-steeps; powder is a one-and-done that you drink as a cloudy, fuller cup.
€4-12 (about $5-13) per 100 g; plain turmeric powder or cut root is inexpensive, with organic, single-origin grades and golden-milk blends at the higher end. Caffeine-free.

Ginger
Ginger is turmeric's natural partner, another warming rhizome; ginger brings bright heat and turmeric brings earthy color and body, the backbone of golden-milk and wellness blends.
Licorice Root
Licorice root is often added to turmeric blends to sweeten them naturally, balancing turmeric's earthy, faintly bitter edge without any sugar.
Masala Chai
Masala chai is the caffeinated, black-tea-based spice drink turmeric sometimes joins; on its own, turmeric is caffeine-free and earthier, lacking chai's tea backbone and sweetness.
Turmeric's golden color is so potent it has been used as a textile and food dye for centuries, and the same curcumin pigment that brightens curries will happily stain your mug, your spoon, and your fingers if you are not careful.
