Valerian (Valeriana officinalis) is a perennial herb that is native to Asia and Europe.

It can grow up to 5 feet (1.5 metres) tall and produces white or pink flowers that are great for attracting pollinating insects to your garden.

Valerian roots have been used for centuries to make herbal remedies, and they are still widely used today.

Valerian has a distinctive smell that some people find unpleasant but I actually like the aroma of a nice cup of valerian tea.

Valerian root can be used to make herbal remedies for insomnia, anxiety and other nervous system problems.

When to harvest valerian roots

Harvesting valerian root is best done in the fall when the plants have finished growing for the season.

How to harvest valerian roots

Cut the stems off near the base of the plants using a pair of garden shears.

This makes it easier to access the roots.

Gently dig up the roots of each plant you’ve chosen to harvest using a spade or garden fork to lift the roots from the soil.

If the roots break off you can use your hands to gently remove the remaining roots.

Shake off the soil and then rinse the roots with your garden hose.

After the roots have been rinsed you can bring them into your kitchen and pat them dry using a paper towel.

How to dry valerian roots

There are a few different ways to dry valerian roots:

1. Dehydrating

One of the fastest ways to dry valerian roots is to use a dehydrator.

Spread the roots out on the trays and it should only take about three hours for the roots to be fully dried.

2. Oven drying

If you don’t have a dehydrator you can lay the roots on a sheet in a single layer and dry them in your oven.

Use the lowest temperature setting and check the roots every hour until they’re dry.

3. Hanging

Group the roots into small bunches and hang the bunches by their stems using string.

Leave them for a week or two until they’re fully dried.

4. Air drying

Lay the roots on a plate or tray and leave it somewhere that is dry and has plenty of air flow.

It will take about two weeks for the roots to dry out.

How to use valerian roots

Once the roots are completely dried, remove the dried roots from the stems.

Roughly chop the roots into small pieces or use a mortar and pestle or spice grinder to turn the dried root into a powder.

Dried valerian root can be stored in an airtight container for up to two years.

The best way to use dried valerian root is to make herbal tea.

To do this, use one teaspoon of dried root per cup of water and steep for 5 to 10 minutes in boiling water before straining the roots and drinking.

You can also use powdered valerian root to make your own herbal capsules.

    Hi I have some really big fat old rhizomes/roots. Will they be any good and if so could I grate them then dry in the oven?

    1. Kelly Martin

      Hi Vic, yes the larger roots are still ok to use. I chop them up before drying them.

    This Fall I dug up one of my Valerian root balls.
    I washed and dried the root by my wood stove for several days..
    As I trimmed the roots into a jar I came to the one hard knot that could no longer give up any roots.
    I first thought to pitch that little hard knot but then had second thoughts.
    I cut it in half with a knife and put each portion in a cup of good potting mix, watered them and set them in a window.
    To my surprise, in a matter of a week little green sprouts appeared through the soil.
    Right now I have wonderful little Valerian Plants waiting to go back to the garden this spring.
    What a wonderful surprise.
