A woman's menstrual blood is extremely powerful.  The earth responds to it with fertile energy and protection. If you put menstrual blood on your land, it will be blessed, in a sense- especially homes and farms. 

Even a small amount will cover a large area of land. A simple drop at each corner of your parameters will draw a connection.  

Putting yourself/ minerals/ energy/ magick/spirit into a place where you live, seek comfort/safety, or work to become agriculturally self sufficient or providing for others- creates love, the most positive energy.
