Most Solanaceae members have alkaloids, groups of complex chemicals, in their roots, leaves and flowers. Alkaloids can be hallucinogens, stimulants or out-right toxic. When potatoes are exposed to light solanin is produced, showing as a green tinge.
In the 20th century, researchers discovered the plant contains dozens of alkaloids: some of them lower blood sugar levels (providing folk remedies with scientific provenance) and blood pressure.
The plants in this family contain a poisonous glycoalkaloid known as solanine that is highly toxic even in small amounts.
The leaves and stems contain a toxic alkaloid and are reported to be poisonous to browsing animals - and the seeds are toxic to children. In Mexico, a stew made of lantana leaves - presumably Lantana horrida -- is used for stomach aliments.
Below ground, plant roots release amino acids, vitamins, sugars, tannins, alkaloids, phosphatides, and glucosides into the soil, affecting plants either positively or negatively, resulting in plant health, or disease.

80 to 90 percent relative humidity for one to two weeks.
Don't wash potatoes you want to store—simply brush off the soil after it dries.
Avoid exposing potatoes to light, which makes the tubers turn green and produce dangerous alkaloids.
Be sure to wear a dust mask when applying it and, as with all pesticides, follow precautions listed on the product labels. In addition, several of the alkaloids in sabadilla can cause rapid depression of blood pressure in mammals.
Caveats: Tomato and rhubarb leaves contain alkaloids, which are toxic to humans, too. Wear gloves when handling the peppers and the pepper spray bottle, as it could burn your skin. Keep these out of the reach of children or pets.
