A covalent HH bond is the net result of attractive and repulsive electrostatic forces.

Saffron is a plant. The dried stigmas (thread-like parts of the flower) are used to make saffron spice. It can take 75,000 saffron blossoms to produce a single pound of saffron spice. Saffron is largely cultivated and harvested by hand. Due to the amount of labor involved in harvesting, saffron is considered one of the world's most expensive spices. The stigmas are also used to make medicine. Saffron is used for asthma, cough, whooping cough (pertussis), and to loosen phlegm (as an expectorant).
