Algae (ascophyllum nodosum)
Synopsis of algae
Algae are a diverse group of photosynthetic aquatic organisms that range from microscopic single-celled forms like chlorella and spirulina to large seaweeds such as kelp and bladderwrack. They thrive in both freshwater and marine environments and are considered some of the most nutrient-dense natural foods on earth. Algae are rich in chlorophyll, protein, essential fatty acids (including omega-3s like EPA and DHA), vitamins (especially B12 in some species), minerals (iodine, iron, calcium, magnesium), polysaccharides, and antioxidants such as phycocyanin and astaxanthin.
In modern herbal and nutritional medicine, algae are used for a wide range of benefits. Spirulina and chlorella are popular superfoods known for their detoxifying, immune-modulating, and anti-inflammatory properties. They support energy, cellular regeneration, heavy metal removal, gut microbiome balance, and cardiovascular health. Kelp and other brown seaweeds are valued for their iodine content, essential for proper thyroid function. Red algae, like dulse, may support skin health and provide rare marine minerals such as vanadium.
Algae also possess antiviral and antimicrobial compounds, and certain species are being studied for their role in blood sugar regulation, cholesterol reduction, and even cognitive protection. Their high chlorophyll and antioxidant content contribute to free radical scavenging, making them useful in anti-aging protocols. Additionally, some species like blue-green algae produce bioavailable B vitamins, trace elements, and enzymes that enhance overall nutrient absorption and vitality.
Historical Use:
The medicinal and nutritional use of algae dates back thousands of years across multiple cultures. In Aztec civilization, spirulina (harvested from Lake Texcoco) was made into cakes called tecuitlatl and consumed for strength and stamina. In Africa, similar practices were observed at Lake Chad, where locals harvested blue-green algae for nourishment.
In China and Japan, seaweeds like kombu, nori, and wakame have been dietary staples for centuries, valued for their mineral content, detoxifying properties, and support of the kidneys and thyroid. In Traditional Chinese Medicine (TCM), seaweed was prescribed to soften hardened masses, resolve phlegm, and treat goiter, recognizing its iodine-rich nature long before the element itself was identified.
In Celtic and Nordic traditions, seaweed was consumed to support digestion, endurance, and recovery from illness. Irish moss (Chondrus crispus), a red algae, was used as a traditional remedy for coughs, bronchitis, and gastric ailments. In Ayurvedic texts, freshwater algae are occasionally referenced for their rejuvenating and detoxifying effects, often grouped with green, bitter herbs that cleanse the body.
Today, algae are used worldwide in superfood powders, detox formulas, immune blends, and thyroid-support supplements, continuing a long legacy of their use as foundational, mineral-rich botanical allies that bridge nutrition and medicine. Their ability to support detoxification, immunity, and cellular health has made algae a cornerstone in both traditional and modern wellness systems.
