How about Nutmeg or just elemicin and myristicin? Either or.
MACMILLAN DICTIONARY OF TOXICOLOGY:
"...The spice (5-15g) causes symptoms similar to atropine poisoning:
flushing of skin, tachycardia, absence of salivation..."
MARTINDALE THE EXTRA PHARMACOPOEIA TWENTY-NINTH EDITION:"...Adverse Effects
Nutmeg, taken in large doses may cause
nausea and vomiting, flushing, dry mouth, tachycardia, stimulation of the central nervous system possibly with epileptiform convulsions, miosis, mydriasis, euphoria, and hallucinations.
Within 4 hours of taking 28 g of nutmeg in water and orange juice, a 19-year-old woman felt
cold and shivery. This was followed after 6 to 8 hours by
severe vomiting accompanied by hallucinations. For a week she had
poor concentration and was disorientated.
Within 3 days of receiving ground nutmeg 9 teaspoonfuls daily... ...
dry eyes and mouth, blurred vision, dizziness, tingling, and feelings of depersonalisation and remoteness. The symptoms gradually subsided as the dose was reduced. - G. S. Venables et al.
Ingestion of freshly ground nutmeg 1.5 to 4 g three to four times daily for 2 days by 2 subjects produced
constipation, but no aspirin-like effect on biphasic platelet aggregation was noted. Both subjects also felt
light-headed, slightly disorientated, occassionally nauseated, flushed, and had nasal congestion and very dry mouths; pupil size was unaffected."

Myristica Fragrans: An Exploration of the Narcotic Spice by Ibo Nagano(originally published in The Entheogen Review also found
here)
"
hysiological effects include dry mouth, nausea, tachycardia, cutaneous flushing, paresthesia, hypotension, euphoria, detachment, CNS excitation, hallucinations, and dyspnea. Nutmeg does not cause any obvious effect on pupil size..."
"... higher doses the effects are more similar to those of the tropane alkaloids,
causing confusion, disorientation, and hallucinations."
Compiled from all of the above:
Short Term: Dry eyes/mouth, blurred vision, dizziness, severe vomiting, tachycardia, flushing skin, nausea, constipation, nasal congestion, parasthesia, hypotension, dyspnea, death(+), dehydration.
Of course Hallucinations, CNS excitation, detachment and a few others could be considered positive whereas with others maybe not so I didn't include those...
I'm pretty certain that by the end of this thing Nutmeg may well have the longest list of any.
+ I have read in a couple places of death as a result of nutmeg poisoning so that should also be listed. I'll site those references later if necessary. EDIT: The first is of an eight year old boy with an equivalent of 560mg/kg myristicin. The second death was a fifty five year old woman who also had Rohypnol in her blood. I'm not so sure death is much more of a risk that anything else at an extremely high dose is.
There are obviously issues with nutmeg and administration. First would be it's incredibly long time for initial onset to occur and then it's incredibly long duration of action. Plus, while it is quite pleasant at low doses,(IME), if one wants to experience the more intense aspects of nutmeg it can be a pain in the butt ingesting such a large amount of material.
Also I should be sampling some Amanita Muscaria tomorrow night (might become a yearly Christmas day thing) so even though their effects are probably well documented already I'll still make sure to report any negative side effects I experience.
And same goes for Methoxetamine which I will should be trying in the next couple days. Whether that should go on the list or not I don't know.
