Hibiscus for mood, lowering blood pressure, and exercise performance

hibiscus-flower

Flowers of Hibiscus (rosa-sinensis Linn) popularly known as “China-rose flowers” contain significant flavonoids (such as anthocyanin and quercetin) known to have antidepressant activity[1].

The antidepressant effect may be from its antioxidant activity[2]; there are few controlled studies on human populations. Hibiscus has been used in Hawaiian cultures to treat postpartum depression[3].

Another herbal tea, made from the sepals of Hibiscus flowers are beautiful, showy red flowers that are harvested and dried like most teas.  This plant contains bioflavonoids, which are believed to help prevent an increase in LDL cholesterol, and to lower blood pressure[4].  The research is quite clear on these effects. It may work by boosting nitric oxide production, generally an advantage for cardiovascular activities (aerobic exercise).

Again, why bother to make tea with this food and limit the nutrient availability when you can eat it! I use a heaping tablespoon in my morning smoothie. I also like to blend it with green tea and ice, then strain it into water bottles as a drink during exercise.

Ashwagandha roots for exercise recovery, insomnia, and cognitive health

 

Ashwagandha-Roots-1030x667

The root of Ashwagandha (Withania somnifera) is used extensively in Ayurveda, the classical Indian system of medicine, and is categorized as a rasayana, an herbal remedy used to promote physical and mental health[1].

There are many claims concerning the health benefits of Ashwagandha root and most all of them concern reduction of adrenal stress (anxiety) and reduction of inflammation; there are many peer reviewed studies, including systematic review summaries that are rather convincing.  Positive influences on neurodegenerative diseases such as cognitive decline and dementias have been suggested[2].

It is likely helpful to ingest this substance after exercise, particularly endurance workouts or heavy lifting (supposedly it helps to stimulate muscle recovery).

Also this Ayurvedic has been used to help treat insomnia.

The amount suggested by the literature studies is one-half teaspoon, about 1600 mg.

Rhodiola for physical and mental performance

160x-rhodiola

by Richard Aiken MD PhD @rcaiken

A systematic review of numerous randomized placebo-controlled studies of Rhodiola rosea showed beneficial effects on physical performance, mental performance, and in mild to moderate depression[1]. For example, one Swedish phase II randomized placebo-controlled study over a six-week clinical trial concluded[2]:

“R. rosea possesses a clear and significant anti-depressive activity in patients suffering from mild to moderate depression. When administered in a dosage of two tablets, each containing 170 mg of extract, daily over a 6-week period, statistical significant reduction in the overall symptom level of depression as well as in specific symptoms of depression, such as insomnia, emotional instability and somatization, could be demonstrated. In higher doses, four tablets per day over a 6-week period, an additional positive effect could be shown. No side-effects resulting from treatment could be detected in any group of the groups”.

Therefore, doses of about 300 – 600 mg were effective in that study.

The mechanism of action may be inhibition of monoamine re-uptake (such as serotonin, dopamine and noradrenaline), enhanced binding and sensitization of serotonin receptors, monoamine oxidase inhibition, and neuro-endocrine modulation[3].  Rhodiola is apparently adaptogenic, meaning that it does its good deeds without disturbing normal biologic functions.

I’m not sure if it is an herb (plant leaf, stem, or flower used for flavoring or medicinal use) or a spice (same as herb but a root).  The aerial portion (above ground plant) is used as a food. However, various alternative names for the plant include “root,” such as the “red root” and the powder is a deep red so I assume that the medicinal part is primarily a root and therefore technically a spice.

Rhodiola Rosea 3% Salidroside Powder (100 grams) costs about $18[4].  I use a little less than one eighth of a teaspoon, about 300 mg (a cost of about ten cents).  I’m unsure of where this was harvested although it can grow on cold rocky slopes in the USA; it has been suggested to aid those living in very cold stressful environments where it grows, such as Siberia and Scandinavia. It has a shelf life of three or more years.
