Due to a mixup, alba was treated like a fake version of viridis.
Alba was allegedly used by the Uniao do Vegetal (UDV) Church in Brazil.
Psychotria catharginensis: The leaves of this species are frequently used in place of Psychotria viridis as a component of ayahuasca brews. According to the Makuna Indians the consumption of the fruit of this species will cause altered perception for several days, however accompanied by nausea, weakness and even fever.
Dried Psychotria vidris contains about 0.10-0.66% alkaloids. Approximately 99% of that is dimethyltryptamine (DMT). Other alkaloids such as beta-carbolines and NMT have been found. The alkaloid content is said to be highest in the morning. -wiki Psychotria Alba seems to grow well, and about twice as fast as Viridis, with about .1 % alkaloid content. The squirrels report a nice light yello crystal with the Psychotrias, and a very PURE, unlimited, light experience. enthogen.com user
Absence of alkaloids in Psychotria carthagenensis Jacq. (Rubiaceae).

Psychotria viridis and P. carthagenensis are often discussed in relation to the hallucinogenic beverage Ayahuasca, used for religious, medicinal and social purposes. The significance of including Psychotria species in this beverage has been understood on the basis of substantial amounts of tryptamine alkaloids detected on leaves of both P. viridis and P. carthagenensis. Nevertheless, there is a long lasting debate over the identification of which Psychotria species are actually traditionally employed. We here report that a P. carthagenensis leaf ethanol extract was found to be devoid of alkaloids. The extract significantly decreased mice body temperature (350 and 500 mg/kg). Toxicity assessment revealed that the extract induced sedation and slight ptoses (75% of animals treated with 1000 mg/kg). Lethality was not observed within 48 h. The data indicate that P. carthagenensis does have bioactive compound(s), possibly active at the central nervous system, but unlikely to be tryptamine alkaloids as in the case of P. viridis. Therefore, if P. carthagenensis is indeed used by ayahuasqueros, its chemical and pharmacological significance have yet to be elucidated. AND ...Sometmes a related species, P. carthaginensis, is used in place of P. viridis as an ayahuasca additive, and two uncharacterized species of Psychotria known as batakawa and pishikawa are so used by the Peruvian Sharanahua (Rivier and Lundgren 1972; Schultes and Raffaul 1990). Cashinahua indians reportedly used two unidentified Psychotria species, one of which matsu kawa, was devoid of alkaloids and doubtless corresponds to the Sharanahua batsikawa, said to be inferior (Der Marderosian et al, 1970). Although Rivier and Lundgren detected DMT (in higher quantities than they found in P. viridis, together with traces of MMT and MTHC) in a sample of P. carthaginensis (Rivier and Lundgren, 1972) the McKenna group failed to replicate this finding with a single sample of yage-chacruna from Tarapoto, Peru, which was 'tentatively' (or with some reservations) identified as P. carthaginensis (McKenna et al 1984A)..." (Pharmacotheon, J. Ott, Natural Products Co. 2nd edition, densified, 1996, pg 220).
the biggest problem to this question is the likely fact that in most studies the plants are often misidentified i would think. Now alba/carth are synonymous by many, not by others....and seems no one really knows how to truly ID them that use them. i have many "viridis" sent form various people in SA and they are all alba/carth group...and have been used a lot with great success....And seeing how well alba grows, it jsut seems more logical to use that one seen as how powerful and easy it is.
but as to actual percents...not sure as any study i have read didnt convince me they knew what species they were testing.
