Medicinal Summer Flowers

Key Points [TL; DR]

The Process of Dehydration

How does dehydration work? It’s quite simple. I use my trusty Nesco dehydrator to dry out a variety of items, and I’ve even written an article on how to make cloth liners or covers for dehydrator racks.

These are a cinch to make and can be adjusted to fit any dehydrator. But let’s focus on the new additions to my dehydrating collection: lavender, roses, nasturtium flowers, red clover, honeysuckle flowers, and valerian flowers.

Summer Flowers

Even though I’ve been drying valerian leaves for some time, adding their flowers is a recent development. I’ve left the flowers on my largest valerian plant, which stands at a staggering 9 feet, alone because I’ll be collecting its seeds.

Alongside these, I’ve also been dehydrating rhubarb. It’s astonishing how much space you can save by dehydrating. For instance, I can fit 16 stalks of dehydrated rhubarb into one jar. However, if I were to freeze them, only two could fit. But I do still freeze quite a few, as they’re perfect for making creamsicles.

Health Benefits of Dehydrating Medicinal Summer Flowers

The advantages of dehydrating flowers extend beyond their preserved beauty. Many flowers carry medicinal properties that can support our health in numerous ways. Let’s take a look at some of the flowers mentioned earlier and explore their health benefits:


Lavender, renowned for its relaxing fragrance, is more than just a lovely garden addition. It has a range of uses that make it an indispensable part of any natural remedy collection.

Red clover is known for its efficacy in treating psoriasis and eczema, and I’ve been adding dehydrated red clover to my soap recipes and my special herbal-infused oil used in my homemade skin cream.


Now, the nasturtium flowers are particularly interesting. These beauties not only add color to your garden but also have wonderful uses in skin and hair care products.


For instance, I use them in my homemade shampoo and in some of the soaps I sell in my store. Nasturtiums are also known to promote hair growth, which can be helpful for people dealing with hair loss.

Nasturtiums, while commonly used in salads for their peppery flavor, also have multiple medicinal benefits:


Valerian, primarily known for its sedative effects, is more than just a sleep aid:

By incorporating these tips into your dehydrating process, you can enjoy the therapeutic benefits of medicinal summer flowers year-round.

Tips for Harvesting and Using Dehydrated Flowers

To maximize the production of flowers for dehydration, it’s crucial to harvest them right away. Once the flowers (and hence the seeds) are removed, the plant is stimulated to produce more. This leads to an increased yield of flowers.

As for usage, dehydrated valerian flowers make a wonderful tea with a pleasant taste and aroma. They have similar benefits to the root, including being sedative and relaxing. In addition to flowers, the leaves of young valerian plants are also beneficial and can be used immediately.

Lavender flowers have antibiotic properties and are excellent for skin health. The key to harvesting lavender is to do it before the little buds on the flower stalks open up. This ensures maximum benefits.

Then we have the roses. While they are often harvested after they open up, harvesting them early can have its advantages, like a more pungent aroma and potentially more potent benefits.
