Mullein is an herbalist's go-to plant for respiratory conditions and it's no wonder why! In traditional medicine, mullein flowers and leaves are used for coughs, colds, bronchitis, and the flu. If you'd like to try your hand at brewing mullein tea, we've got you covered! In this article, we'll walk you through the process of steeping and flavoring mullein so you get the perfect cup.

How do you make mullein tea?

Tea expert Kelly Miller says you brew mullein tea the same way you do any herbal tea. Use 1-2 tsp (5-10 g) of dried mullein for every 1 cup (240 ml) of water, and steep for 10-15 minutes. Strain the tea through a filter to remove leafy solids, and drink up to 4 cups (950 ml) per day to soothe a sore throat or cough.

Place 1 to 2 teaspoons (5 to 10 g) of dried mullein in a pot. Use 1 teaspoon (5 g) for weaker tea that has a milder taste. If you'd like stronger mullein tea, put 2 teaspoons (10 g) in a small pot or a heat-safe container that's easy to pour from.
- Use the leaves, the yellow flowers, or a combination if you're harvesting your own mullein. Brewing with just the flowers makes sweeter tea.
- It is possible to use fresh mullein leaves, but you'll need to steep the tea for 20 to 30 minutes and it won't be as strong.
- If you'd like to make a larger batch, feel free to double or triple the amount of mullein leaves. Just remember to add more water, too!
Add boiling water and steep the tea for 10 to 15 minutes. Pour 1 cup (240 ml) of water over the dried mullein. Then, cover the pot and let the tea steep—the longer it steeps, the stronger it will be. The tea also cools a little as it steeps so it will be perfect for sipping!

Strain the tea through a coffee filter. Line a fine-mesh strainer with a coffee filter or cheesecloth. Set the strainer over a serving mug and slowly pour the mullein tea through the filter. The filter catches prickly hairs from the leaves.^{[1]

- It's fine to serve the tea unfiltered, but many people find that the tiny hairs scratch their throats.

Mint adds a fresh flavor that can mask mullein's earthy taste. Mint or spearmint hides the natural flavor of mullein—add a few fresh mint leaves or drop 1 mint tea bag into the pot with the dried mullein.^{[2]

Add honey or maple syrup to your mullein tea for a little sweetness. Honey has been used for thousands of years to treat colds. It has antibacterial and anti-inflammatory properties, but if you don't like honey, you've still got lots of options for sweetening your tea. Here are a few things you could add to sweeten your mullein tea:
- Fruit juice
- Simple syrup
- Flavored syrup like vanilla syrup
- Stevia
- Agave syrup

Most herbalists scrub the root, dehydrate it, chop it, and use it to make a mullein tincture instead of tea.
