About

Bacopa, also known as Water Hyssop or Brahmi, is a creeping succulent perennial that can grow to about 20 inches. It features spatula-shaped fleshy leaves and pale blue or white flowers on slender stalks. Thriving in marshlands and along the edges of mangrove swamps in warmer temperate and tropical climates - especially southern Asia - it develops into dense mats on mudflats. This herb has been a cornerstone of Ayurvedic medicine for supporting cognitive function and treating various nervous system disorders, and it is increasingly recognized in Western herbalism for its brain-enhancing properties.

Lobelia is an annual herb growing to 20 inches with lance-shaped leaves and pale blue, pink-tinged flowers. A powerful antispasmodic used for respiratory and muscle disorders, it was a traditional Native American remedy for many conditions. It was used as a 'puke weed' to induce vomiting, as a remedy for worms and venereal disease, and as an expectorant. Lobelia was also smoked as a substitute for tobacco and was reputed to share some of its magical qualities. Indigenous to North America, especially eastern parts of the United States, it grows by roadsides and in neglected areas, preferring acid soil. The aerial parts are harvested in early autumn when the seed capsules are most numerous and are carefully dried. Its use was later championed by the American herbalist Samuel Thomson (1769-1843), who made the herb the mainstay of his therapeutic system, mainly using it to induce vomiting.

Safety & precautions

Not recommended for individuals with hyperthyroidism, as bacopa may influence thyroid function. Generally well-tolerated in normal use, with recent toxicological studies indicating it is relatively safe. No significant drug interactions have been documented, though it contains flavonoids whose interactions should be considered on a case-by-case basis. Avoid during pregnancy and lactation unless under professional guidance.

Take only when prescribed by a medical herbalist or doctor and do not eat the fresh plant. Excessive ingestion is rare (vomiting normally occurs first) but can be fatal. Restricted herb in some countries. The FDA considers lobelia to be poisonous, and many sources claim it will cause convulsions, coma, and death. These are potential effects of its principal alkaloid lobeline, but there is no record of the whole herb causing these problems in anyone. Lobelia is an emetic and makes you throw up if you take too much. It can produce severe symptoms (nausea, profuse sweating, vomiting, and deep relaxation), but these symptoms typically pass quickly and the person feels better afterward. However, because of these effects, lobelia is not recommended for weak, debilitated persons or persons who are deeply relaxed. Not recommended for long-term use and should be used cautiously during pregnancy. To avoid unpleasant effects such as nausea and vomiting, use small, repeated doses instead of large, infrequent doses, or use it as part of a formula.
