Improper use of hyssop can cause side effects such as allergic reactions, diarrhea, and stomach cramps. High doses of the plant can also cause kidney damage and interact with certain medications, such as blood thinners and diabetes medications.

Precautions when using hyssop medicinally include consulting a healthcare professional before use, especially for individuals with allergies or medical conditions.

Hyssopus officinalis grow best in well-drained soil and full sun, requiring at least 6 hours of direct sunlight per day. They thrive in alkaline to neutral soil pH (6.0-7.0) and can tolerate some shade, but growth is impaired.

When planting hyssop, sow seeds 1/8 inch deep and 12-18 inches apart in the spring or fall. Water thoroughly after planting and keep the soil consistently moist during the first growing season. Space mature plants 18-24 inches apart to allow for air circulation.

Hyssop flowers can be harvested when in full bloom, typically in mid-summer. Pinch or cut off individual flowers to promote further blooming. Harvest the leaves and stems regularly to encourage new growth and prevent the plant from flowering too much.
