This herbal remedy for ADD / ADHD is aimed specifically at adults and they claim it will:
- Improve focus and ability to concentrate
- Increase attention span
- Boost memory functioning
- Increase motivation and energy levels
- Increase study skills
- Boost immune functioning and protect against illness
- Reduce distractibility
Centrella Asiatica has been linked with increase blood flow and healing in wounds and also with cognitive improvements. However these studies are all animal related and nothing to do with ADD / ADHD. Whilst Rosemary tastes delicious with lamb there it nothing to indicate it can help with ADD / ADHD. There is some speculation that chemicals in Rosemary will inhibit acetylcholinesterase that play a part in memory but there is no direct evidence to support it.
Ginsing is more complicated because there has been a reasonable amount of research done on it. Starting in the 1940’s in Russia, Ginsing was taken by the Soviet olympic team and since the cold war ended, it has been studied in the West. However its effects, if any, appear subtle because some studies find significant reductions in stress and improvements in quality of life, but other studies find no benefit.
Looking at the herbs used in Focus ADDult it seems to me that they have included three herbs with only the remotest link to ADD / ADHD. I suspect their inclusion was far more to do with price and availability than scientific evidence of their effectiveness on ADHD.
Research: Effect of Centella asiatica on cognition and oxidative stress in an intracerebroventricular streptozotocin model of Alzheimer’s disease in rats; Double-blind study of a multivitamin complex supplemented with ginseng extract.
