Cats Claw in the following reports is a powerful immune system modulator or heals the immune system. One report claims it will reverse Parkinson disease.

1. "Claw products may contain as much as 80% TOAs, and as little as 1% TOAs can cause a 30% reduction in immune system modulating properties that POAs provide...Even a normal functioning immune system is unable to attack and eliminate Bb in all its forms. The results of research on TOA - f ree Chemotype Cat’s Claw demonstrate its powerful immune system modulating and stimulating properties, along with pronounced anti-inflammatory, antioxidant, and anti-infectious effects. The diverse spectrum of the biological activities of TOA - free Chemotype Cat’s Claw is due to its biologically active compounds. The pentacyclic oxindole alkaloids (POAs) contained in this Chemotype are generally accepted as the principal immunomodulating and immunostimulating agents. POAs are actively involved in the repair of many elements and functional mechanisms of both the innate and acquire d immunity damaged by Bb and other coinfections, assisting in restoration of structural and functional integrity of the immune system, enhancing its ability to eliminate the pathogens in a natural way. In addition, this Chemotype contains quinovic acid glycosides – compounds with strong natural antibiotic properties (the latest generations of conventional synthetic antibiotics, “Quinolones,” are based on quinovic acid glycosides), which further enhance the medicinal effect of TOA - free Chemotype Cat’s Claw in fighting the infection...Since about 90% of these forms reside in various cells (including all blood cells) which have a life-span of 2-3 weeks to 6-8 months, it may be assumed that within a 6-8 month period, a significant majority of all intracellular forms of Bb will be released into the environment where they can be successfully attacked by a properly functioning immune system and a natural powerful antibiotic."

2. "Antigenotoxic, antioxidant and lymphocyte induction effects produced by pteropodine. Paniagua-Pérez R, Madrigal-Bujaidar E, Molina-Jasso D, Reyes-Cadena S, Alvarez-González I, Sánchez-Chapul L, Pérez-Gallaga J.Laboratory of Muscular Biochemistry, National Institute of Reahabilitation, National School of Biological Sciences, I.P.N., Carpio y Plan de Ayala s/n, Sto. Tomás, D.F., Mexico.

Pteropodine is a heterohimbine-type oxindole alkaloid specifically isolated from 'Cat's claw' (Uncaria tomentosa), a plant that has shown cytostatic, anti-inflammatory and antimutagenic properties and is used in traditional medicine to cure a number of diseases. In this report, we studied the ability of pteropodine to decrease the rate of sister-chromatid exchanges and micronucleated polychromatic erythrocytes in mice administered doxorubicin. We also determined its capacity to induce lymphocyte production in mice as well as its free radical scavenging potential by applying the DPPH assay. We found pteropodine (100-600 mg/kg) to significantly decrease the frequency of sister-chromatid exchanges and micronucleated polychromatic erythrocytes in mice administered with 10 mg/kg of doxorubicin. Furthermore, we determined that pteropodine partially corrected bone marrow cytotoxicity induced by doxorubicin, as it showed an improvement in the rate of polychromatic erythrocytes. Besides, 600 mg/kg of pteropodine increased 25.8% of the production of lymphocytes over the control value along a 96-hr assay, and it exhibited a strong capacity to trap the DPPH-free radical (98.26% with 250 microg/ml). Our results establish that pteropodine is an effective antimutagen in the model used, and suggest that pteropodine deserves further research in the area of cell protective potential and its mechanism of action."PMID: 19175366 (2)

2. "Reversible worsening of Parkinson disease motor symptoms after oral intake of Uncaria tomentosa (cat's claw). Cosentino C, Torres L.Movement Disorders Unit, Instituto de Ciencias Neurologicas, Ancash 1271, Lima 1, Peru.

Uncaria tomentosa (UT), also known as cat's claw, isa Peruvian Rubiaceae species widely used in traditional medicine for the treatment of a wide range of health problems. There is no report about the use, safety, and efficacy of UT in neurological disorders. We describe reversible worsening of motor signs in a patient with Parkinson disease after oral intake of UT, and some possible explanations are discussed." PMID: 18836348 (3) (This is a very significant statement that cats claw reverses Parkinson disease.)

2. "A review of DNA repair and possible DNA-repair adjuvants and selected natural anti-oxidants. Emanuel P, Scheinfeld N.Mount Sinai Medical Center, New York, New York, USA.

Few other organs have the environmental exposure-neoplasia relationship that has been observed between epithelial cutaneous malignancy and UVB exposure. A significant DNA type of defective linking of DNA nucleotides involves pyrimidine dimers. Important insight into the molecular processes that affect the response of cells to UVB have been provided by the study of rare inherited diseases characterized by DNA repair defects. Nucleotide excision repair is the best characterized of these and its importance is illustrated by the disease, xeroderma pigmentosum. This heterogenous disorder clinically characterized by malignant tumor development and molecularly by distinct alterations in the nucleotide excision repair apparatus. More recently, other DNA mechanisms have been shown to have some role in skin cancer, such as DNA-mismatch repair and double-stranded DNA breaks. Herein, we discuss the DNA-repair adjuvants a aqueous extract of Urcaria tomentosa (AC-11, Optigenex, Inc.), and T4 endonuclease V that is prepared in a liposome lotion (Dimericine, Applied Genetics Inc. Dermatics). The positive effects on the integrity DNA of other substances (from nature, heat shock proteins and cytokines) including IL-12, Polypodium leucotomos, and ubiquitin are also reviewed. Understanding DNA repair mechanisms is far from complete; further understanding will provide insight into the pathogenesis of cancer and pave the way for efficacious therapeutic agents."
