The branch of economics that examines how economic decisions are made by individual businesses, households, and industries. In contrast, macroeconomics analyzes big-picture economic decision-making throughout the economy and examines the effect that employment or inflation is likely to have on the economy.

Tansy is a common European herb and the scientific name of Tansy is Tanacetum Vulgare or Tanacetum Annuum. The essential oil of Tansy is extracted by steam distillation of all the plant parts. The chief components that form this essential oil are artemisone, borneol, camphone, camphor, isopinocamphone, piperitone, and thujone.
Today, the medicinal properties formerly attributed to tansy have been largely discredited, although it is still in use as an effective insect repellent and can be an asset in the garden as a companion plant for cucumbers, squash, roses and some berries to help keep the plants pest-free.
