Cat’s Claw

Cat’s Claw (Uncaria tomentosa), also known as uña de gato belongs to the Rubiaceae family and it is a large woody vine growing over 30 metres native to the Amazon rainforest and other tropical areas of South and Central America including Peru, Colombia, Costa Rica, Guatemala, Panama and other.

This herb has been used historically by the indigenous peoples of the Amazon such as the Asháninka for at least 2,000 years to treat asthma, inflammations of the urinary tract, arthritis, rheumatism and bone pain.

Since the early 1990s Cat’s claw has been used as an adjunctive treatment for cancer and AIDS in Peru and Europe.

Rhodiola (Rhodiola rosea)

Rhodiola is an adaptogen used for centuries to improve physical endurance, memory, work productivity, energy, sexual stimulation and reduce altitude sickness. It is an antioxidant, immune stimulant, antidepressant, anti-anxiety and helps with insomnia.


It is believed that Rhodiola works via neurotransmitter activity such as serotonin, norepinephrine and dopamine within the brain stem, cerebral cortex and hypothalamus.

I usually combine it with St John’s wort to treat depression, Withania for anxiety or Withania and Siberian ginseng for decreased energy and vitality. Rhodiola standardised to contain 3.0 mg/mL rosavins and 1.0 mg/mL salidroside is available in 200mL through Herbal Store.

Peony (Paeonia lactiflora)

PeonyThe active constituent in Peony seems to be paeoniflorin, a monoterpene glycoside. It is thought to act directly on the ovary to reduce the production of androgens in a dose-dependent manner. It increases the activity or aromatase, which promotes the synthesis of oestradiol from testosterone thus lowering serum testosterone levels. It also seems to regulate the LH to FSH ratio.

Formulas containing Peony may also improve progesterone levels by normalizing ovarian function when the activity of aromatase is inhibited. It has been used to treat hyperprolactinaemia, ovarian failure and androgen excess. The biofeedback in the pituitary and hypothalamus rely on aromatase to regulate prolactin and GnRH.

It is indicated in infertility, irregular cycles and ovulatory failure such as in PCOS, any hormonal irregularity including elevated androgens, low progesterone, high or low oestrogen and elevated prolactin.

Tribulus (Tribulus terrestris)

Tribulus terrestris

Tribulus is a male sexual tonic, enhances the motility of spermatozoa and increases sperm count. Clinical studies have shown improvement in libido, sexual activity and intracavernous pressure in rats (2.5–10 mg/kg/day), and a proerectile effect on corpus cavernosum smooth muscle of rabbits (tissue isolated after treatment, 2.5–10 mg/kg/day). Also, there was a marked stimulation of spermatogenesis, increased density of Sertoli cells, increased tenacity and viability of spermatozoa, and accelerated and emphasised sexual activity in rats (70 mg/kg/day). Female rats treated with the saponin fraction produced more offspring. It is therapeutically used in erectile dysfunction, low libido in both sexes, menopause and male infertility.

Many Tribulus products on the market are quite different in phytochemical profile from the Bulgarian extract. Only leaf from Bulgaria was high in protodioscin (the active ingredient of Tribulus).

Dong quai (Angelica sinensis)

Angelica sinensisAngelica sinensis commonly known as Dong quai, has been traditionally used for gynaecological ailments including menstrual irregularities and cramps, retarded flow, PMS and menopausal symptoms. It relaxes and stimulates the uterus at the same time producing a balancing effect and it also has a mild sedative effect on the central nervous system.
