decoctions - tough parts of the plant are boiled in water; the liquid containing the active ingredients is then strained.
tinctures - the herb is soaked in alcohol and water for two weeks, then strained in a muslin-lined wine press.
infusions - the herbs are covered with very hot water and left to steep for ten minutes. The resulting liquid is much like a tea, and may be sweetened with honey.
infused oils - used for massage, these oils may be made by placing the herbs and oil over heat, or they may just be left in sunlight.
creams - oil, water, glycerine and herbs are simmered for several hours, before being strained and left to set.
ointments - oil and herbs are combined over heat, then strained and left to set. These are particularly useful for when the skin needs to be protected from moisture.
Haloperidol use may lead to the development of symptoms that resemble Parkinson's disease, but that are not caused by Parkinson's. These symptoms may include a taut or mask-like expression on the face, drooling, tremors, pill-rolling motions in the hands, cogwheel rigidity (abnormal rigidity in muscles, characterized by jerky movements when the muscle is passively stretched), and a shuffling gait. Taking the anti-Parkinson drugs benztropine mesylate or trihexyphenidyl hydrochloride along with haloperidol help to control these symptoms. Medication to control Parkinsonian-like symptoms may have to be continued after haloperidol is stopped. This is due to different rates of elimination of these drugs from the body.
Results Two hundred forty-seven participants (mean [SD] age,  years; 85 women [%]; 218 with cancer [%]) were included in intention-to-treat analysis (82 receiving risperidone, 81 receiving haloperidol, and 84 receiving placebo). In the primary intention-to-treat analysis, participants in the risperidone arm had delirium symptom scores that were significantly higher than those among participants in the placebo arm (on average Units higher; 95% CI, -; P = .02) at study end. Similarly, for those in the haloperidol arm, delirium symptom scores were on average Units higher (95% CI, -; P = .009) than in the placebo arm. Compared with placebo, patients in both active arms had more extrapyramidal effects (risperidone, ; 95% CI, -; P = .03; and haloperidol, ; 95% CI, -; P = .01). Participants in the placebo group had better overall survival than those receiving haloperidol (hazard ratio, ; 95% CI, -; P = .003), but this was not significant for placebo vs risperidone (hazard ratio, ; 95% CI, -; P = .14).
