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?’.

Protective mechanisms of phytochemicals against Cd and Pb toxicity and their food sources.

PhytochemicalToxic MetalProtective MechanismsRef.Food Sources
Quercetin Cd Quercetin induces eNOS, iNOS, COX-2 and MT expression. [90,91] Onion, tomato, capers and radish
  Pb Quercetin modulates the MAPKs and NF-κB signalling pathway and forms excretable complex with Pb. [92,93,94]  
Catechin Cd Catechin inhibits Cd absorption and normalises bone metabolic disorders through the bone mineral density, bone mineral content and bone calcium content. [95] Tea, cocoa, peach and berries.
  Pb Catechin protects hepatic cell membrane fluidity, increases cell viability and modulates oxidative stress. [96]  
Anthocyanin Cd Anthocyanin protects against Cd-induced oxidative stress. [97] Cherry, grape and berries.
  Pb Anthocyanin appears to effectively diminish oxidative stress. [98,99]  
Curcumin Cd Curcumin protects against Cd-induced lipid peroxidation. [100,101] Turmeric
  Pb Curcumin binds Pb to form an excretable complex, reducing neurotoxicity. [102]  
Naringenin Cd Naringenin quenches free radicals, recovers antioxidant enzyme activity and chelates Cd. [103] Orange, grapefruit and tomato
γ-Oryzanol Cd γ-Oryzanol reduces the testicular Cd concentration, improves ALAD activity and prevents lipid peroxidation. [104] Rice
Puerarin Pb Puerarin modulates the PI3K/Akt/eNOS pathway, reduces reactive oxygen species and protects against DNA damage and apoptosis. [105,106] Pueraria

ALAD, δ-aminolevulinic acid dehydratase; Akt, protein kinase B; COX-2, cyclooxygenase-2; eNOS, endothelial nitric oxide synthase; iNOS, inducible nitric oxide synthase; MAPKs, mitogen-activated protein kinases; MT, metallothionein; NF-κB, nuclear factor kappa B; PI3K, phosphoinositide-3-kinase.
