This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

Type of Spiritual Experience


Osteoarthritis is not the same as rheumatoid arthritis but the pain produced from both is, as such I have added a link to rheumatoid arthritis, for completeness


A description of the experience


Ther Adv Musculoskelet Dis. 2012 Jun;4(3):181-207. doi: 10.1177/1759720X11436238. Current nutraceuticals in the management of osteoarthritis: a review. Akhtar N, Haqqi TM. Department of Medicine/Rheumatology, MetroHealth Medical Center, Case Western Reserve University, Cleveland, OH, USA.

Osteoarthritis (OA) is a progressive degenerative joint disease that has a major impact on joint function and quality of life. Nutraceuticals and dietary supplements derived from herbs have long been used in traditional medicine and there is considerable evidence that nutraceuticals may play an important role in [alleviating] inflammation and joint destruction in OA.

We review the biological effects of some medicinal fruits and herbs - pomegranate, green tea, cat's claw, devil's claw, ginger, Indian olibaum, turmeric and ananas - in an attempt to understand the pivotal molecular targets involved in inflammation and the joint destruction process and to summarize their toxicities and efficacy for OA management.

Ginger, turmeric and pineapple - So far there is insufficient reliable evidence on the effectiveness of ginger, turmeric and ananas.

Pomegranate and green tea - only have preclinical evidence of efficacy due to the lack of clinical data. In vivo and clinical studies are required to understand their targets and efficacy in OA.

Cat's claw and Indian olibaum - Limited in vitro and in vivo evidence is available for cat's claw and Indian olibaum. More extensive studies are required before long-term controlled trials of whole cat's claw and Indian olibaum extracts, or isolated active compounds, are carried out in patients with OA to determine their long-term efficacy and safety.

Devil's claw - has not been rigorously tested to determine its antiarthritic potential in in vitro and in vivo models. There is strong clinical evidence of the effectiveness of devil's claw in pain reduction. However, high-quality clinical trials are needed to determine its effectiveness.

No serious side effects have been reported for any fruits and herbs. Overall, these studies identify and support the use of nutraceuticals to provide symptomatic relief to patients with OA and to be used as adjunct therapy for OA management. More high-quality trials are needed to provide definitive answers to questions related to their efficacy and safety for OA prevention and/or treatment.
