Graceful & Beautiful herb Easy to Grow indoors or outdoors! Has many uses! Cool Beans n Sprouts Brand Hyssop (Hyssopus officinalis) is a plant that's been used medicinally for centuries, possibly even as far back as Biblical times (it's mentioned in the Old Testament). The above-ground parts of the plant are what are used for medicine, not the roots. You may have come across hyssop without knowing it. While it has a bitter taste, it's sometimes used as a flavoring in foods, and the oil is used as a fragrance in some body-care products and makeup. Hyssop is in the Lamiaceae family, which is also known for thyme, mint, oregano, basil, sage, rosemary, lemon balm, and many other aromatic plants.
