- Mitragyna speciosa (commonly known as kratom, an herbal leaf from a tree of the Rubiaceae family) is a tropical evergreen tree in the coffee family native to Southeast Asia. It is indigenous to Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, where it has been used in herbal medicine since at least the 19th century. It has also historically been used for chewing, smoking, and tea. Kratom has opioid properties and some stimulant-like effects.

Birdsfoot trefoil is a moderately long-lived herbaceous perennial legume. It has a well developed, branching, tap-like root with side roots near the soil surface. Most cultivars are erect and grow to a height of 2 to 3 feet. The stems are slender, branch well, and are moderately leafy. Leaves are smooth and consist of 5 leaflets. The bloom is made up of a cluster of bright yellow flowers arranged in a whorl at the end of the flowering stems. When ripe, the brown seed pods extend outward from the stalk and look like a bird’s foot. The plant remains green and succulent during and after seed ripening. There are an average of 375,000 seeds per pound.
