Brown Seaweed


This very interesting form of Brown Seaweed blooms from June to September in the Mediterranean Sea. It has a glowing white appearance that is due to the presence of calcium carbonate deposits on the outside of the algae in the form of aragonite crystals. These crystals are not known to spontaneously develop in the Mediterranean and are normally only formed in controlled conditions. The plants’ ability to fix calcium to its outer structure in this unique and fascinating way has led researchers to see whether this mechanism could be transformed into a biological agent for the same purpose.


The study of the evolutionary development and diversification of a species, or of a particular feature of an organism and how those characteristics are expressed in the development of more complex organisms is called phylogenetics. The algae Padina pavonica in it’s efforts to form a relationship with the sun, produce food through photosynthesis, and fixate it structure in its environment, figured out how to fix calcium into its outer structure in the midst of conditions that made this extremely difficult. It is through our understanding of how plants have made adaptations to survive in their environment that we look for answers to how we may do the same. Some of the constituents in Padina pavonica are being researched for their ability to support the structure and function of bone and connective tissue.*

Ecologically Harvested is a term that describes all herbs sold by Gaia Herbs that are not Certified Organic. Ecologically Harvested herbs include herbs that are harvested in their natural habitat, (i.e., wild harvested) according to specific guidelines for harvesting these herbs (i.e., away from roads and industry, as well as guidelines to avoid overharvesting). Our term, Ecologically Harvested, also includes herbs that are grown in managed woodland areas, fields designated for specific herbs, and herbs that are grown by indigenous growers, such as Kava Kava. All Ecologically Harvested herbs pass pesticide and heavy metal testing as well as microbial testing, prior to release.
