Interesting. I looked up wikipedia and found :
"...From Wikipedia, the free encyclopedia
Genus: Hyptis Jacq.
Species: H. suaveolens
Binomial name Hyptis suaveolens (L.) Poit. 1806
The Chan plant (scientific name Hyptis suaveolens (L.) Poit. ) is a very well known pseudo-cereal plant in the Latin American region, being approximately 2 meters high, having branches and long, white piliferous stems. Its flowers are purple or white, its leaves oval, wrinkled and pointed. It is native to the American continent, in warm and semi-warm regions.
Chan is commonly used as a refreshing healthy drink, by leaving the seeds to soak in water and refrigerating the mix. Some people add lemon or other citrus fruit to achieve a better taste. Chan has also traditionally been used and continues to be used as a treatment for diarrhea.
Studies have found it is effective as an insecticide. Its dried leaves and seeds are ground to a powder which is spread on the grains to be conserved.

Pseudocereals are broadleaf plants (non-grasses) that are used in much the same way as cereals (true cereals are grasses). Their seed can be ground into flour and otherwise used as cereals. Examples of pseudocereals are amaranth, Love-lies-bleeding, red amaranth, Prince-of-Wales-feather, quinoa, and buckwheat.
Quinoa is not a grass. Its seeds have been eaten for 6000 years.

So, in sum this plant is useful as medicine and as food.
