We have the herb Melissa now, in addition to the other herbs. You also know it as Lemon balm. In Germany, it is Zitronenmelisse.
This translates into Lemon Melissa. It is a much-used home remedy, and just about every home had a bottle of "Klosterfrau Melissengeist" in their First Aid remedy kit, which is distilled Melissa spirits. You can duplicate this by making a tincture.

Tinctures are made by soaking a herb in consumable Alcohol with ideally at least 50% alcohol. Vodka will do, even though it's only 40%. You fill a jar with the herb, pack it, but not too tight, until the jar is about 3/4 full, and then pour in the alcohol. Let this sit in a dark place at room temperature and shake daily for about 14 days to a month. You can then strain the herb or decant what you like.

You can use this tincture with a dropper bottle, or measure out a small amount as needed.
If you want to do this and need more info, let me know and I'm happy to tell you more.

Here is why you want to use it, and again, to avoid making medical claims, I found an official, respected site that can.

"Lemon balm (Melissa officinalis), a member of the mint family, is considered a calming herb. It was used as far back as the Middle Ages to reduce stress and anxiety, promote sleep, improve appetite, and ease pain and discomfort from indigestion (including gas and bloating, as well as colic). Even before the Middle Ages, lemon balm was steeped in wine to lift the spirits, help heal wounds, and treat venomous insect bites and stings. Today, lemon balm is often combined with other calming, soothing herbs, such as valerian, chamomile, and hops, to promote relaxation. It is also used in creams to treat cold sores (oral herpes)."

The use in treating cold sores is because it is also an anti-viral. Our interest in anti-viral herbs has become increased since 2020, for obvious reasons. Check out the information on that site. There is much more. Dosage, Interactions, Research etc. I'm always thrilled when I see things like that on respected mainstream medical sites with solid science backup.
However, there is more, but that is enough for now. They mention the use of the Essential Oil of Lemon balm, but don't be fooled. Many offer it, but hardly any are real. This is not a very oily plant and true Lemon balm or Melisssa essential oil is in the price range of Rose Otto. We're talking about hundreds for very, very little. And because it is so expensive, you also need to find a supplier you can trust. Most of these oils are fakes. Just as a side note.

But it is very easy to work with the herb.
Melissa officinalis is a perfect herb to combine with Thyme for example. Both smell wonderful, and Melissa does actually relax, supporting Thyme's effect on the parasympathetic nervous system. Thyme stimulates the immune system, Melissa is anti-viral. And the list goes on. Perfectly complimentary in scent, taste and healing. Both are also culinary extravaganza beyond the standard use of herbs in food. So even if you're not into drinking tea, you can consume them in a very tasty drizzle of sauce or dressing.

I come from a time when information like that, on a medical website no less, was not only nonexistent, but unimaginable. So there is hope apparently, and miracles do happen. And yes, herbs are solid medicine options.

Aside from all that, Lemon balm is such a lemony, refreshing delight, if you decide to make tea with it, salad dressing, infused water, or something else. 

However, know that the intoxicating scent of the fresh herb does lessen a lot, and depending on how sensitive your sense of smell is, it might seem gone. This does not make the herb less potent. The reason is that lemon scents are very fleeting.
